West Ham 2-1 Chelsea, Aston Villa 1-2 Swansea: Barclays Premier League as it happened

That is all from this particular live blog, but stay with IBTimes UK for post-match reaction and click here to follow live coverage of the late afternoon clash between Arsenal and Everton at the Emirates Stadium.

So, yet another dismal afternoon for Chelsea as they slump to their fifth Premier League defeat of the season and seventh in all competitions. That is quite a remarkable regression from last year's dominant title-winning campaign and it remains to be seen how safe Mourinho's position is moving forward despite that recent vote of confidence from owner Roman Abramovich.

As for West Ham, they continue to go from strength under cult hero Bilic and they have now beaten Arsenal, Liverpool, Manchester City since August and move up to second place before the Gunners face Everton later this evening. Their most satisfying start to a top-flight campaign just gets better and better.

West Brom rise to eighth thanks to a solid away performance underpinned by Rondon's goal, while Leicester have now strengthened their grip on fifth thanks to yet another win that was secured by Vardy's latest heroics. Watford will be hugely encouraged by that 2-0 success in the Potteries.

West Ham 2-1 Chelsea

Aston Villa 1-2 Swansea

Leicester 1-0 Crystal Palace

Norwich 0-1 West Brom

Stoke 0-2 Watford

A free-kick in an excellent position for Chelsea in stoppage time is wasted as West Ham block Willian's effort.

Not to be outshone by his slightly younger sibling, Andre Ayew knocks home Naughton's low cross to put Swansea on course for their first victory in all competitions since August.

Sherwood could well be on the brink if Villa cannot muster an equaliser.

Goal: Aston Villa 1-2 Swansea (Andre Ayew)

Just 11 minutes left to play at Upton Park and West Ham have restored their lead against the 10 men of Chelsea as towering striker Carroll, who replaced Zarate midway through the second half, powers home a header from Cresswell's cross.

Goal: West Ham 2-1 Chelsea (Andy Carroll)

Villa are not ahead for long before they are pegged back by a lovely curling free-kick from Sigurdsson. Watford have doubled their lead at the Britannia Stadium as Abdi drills an effort past Jack Butland.

Goal: Stoke 0-2 Watford (Almen Abdi)

Goal: Aston Villa 1-1 Swansea (Gylfi Sigurdsson)

It's a family affair at Villa Park. Just moments after older brother Andre misses for Swansea, Jordan Ayew connects on a diving header to leave the under pressure Sherwood breathing a huge sigh of relief.

Against the odds, Chelsea are level in East London as West Ham struggle to clear Willian's corner and Cahill fires home on the half-volley. Game very much on.

At Leicester, Vardy has become just the eighth player to score in seven consecutive top-flight matches as he lofts the ball past Wayne Hennessey after being teed up by Mahrez. That is quite some achievement for the in-form England forward.

Goal: Leicester 1-0 Crystal Palace (Jamie Vardy)

Goal: Chelsea 1-1 West Ham (Gary Cahill)

Although no official confirmation has been forthcoming over Mourinho's alleged punishment, it appears he is watching the second 45 from the director's box.

West Brom break the deadlock at Carrow Road as record signing Rondon, a £12m arrival from Zenit St Petersburg in August, heads home a James McClean cross from the left-hand side.

Goal: Norwich 0-1 West Brom (Salomon Rondon)

Chelsea have made one change at the break, with John Obi Mikel summoned to replace Fabregas. Mourinho has not taken his seat for the second half and reports on social media claim that he has also been given his marching orders by the officials for an outburst in the tunnel.

A graphic to show just how near that Zouma header came to going in. The whole ball is not over the line, as you can see, but that must be one of the closest decisions made since goal-line technology was introduced to the Premier League.

That did appear to be a fair decision in all honesty, but that won't stop Mourinho from expressing his distaste at the final whistle you would wager. A big second half ahead for Chelsea.

To say that Chelsea were somewhat miffed by that decision would be a colossal understatement. John Terry, Costa and Fabregas were both booked by referee Jonathan Moss for their furious reactions and coach Silvino Louro was sent to the stands.

Half-time

Stoke 0-1 Watford

It's shaping up to be another heinous afternoon for the champions as Matic, sent off during Serbia's Euro 2016 qualifier against Portugal earlier this month, is dismissed for a second bookable offence.

His first caution was for fouling Cheikhou Kouyate as the West Ham midfielder tried to break and the second infringement was spotted by the assistant referee on the far side.

Red card: Nemanja Matic (Chelsea)

Deeney makes up for that initial miss by giving Quique Sanchez Flores' side a first-half lead with a curled effort from the edge of the 18-yard box. That is a first Premier League goal for the Watford captain.

Goal: Stoke 0-1 Watford (Troy Deeney)

A glorious chance for West Ham to double their lead goes begging as the dangerous Zarate lofts the ball over when put clean through.

Still no goals from across the four other 15:00 BST fixtures, but Watford have struck the woodwork twice in quick succession through strike pairing Troy Deeney and Odion Ighalo.

Replays show just how incredibly close that Zouma header was to crossing the line. At the other end, James Collins has seen a tame header easily saved by Begovic.

Agonisingly close for Chelsea as Zouma's header from a Fabregas corner is somehow cleared off the line by Manuel Lanzini.

Aaron Cresswell brings down Ramires and Chelsea have a free-kick 25 yards from goal. Willian has been been very dangerous indeed from these sorts of set pieces this season, but Adrian is alert to dive across and push his effort to safety.

Chelsea are struggling to create any meaningful chances, with only a speculative long-range effort from Ramires to show for their efforts in the last few minutes. A nervy moment for Carl Jenkinson as his header back towards Adrian skips off the wet turf and out for a corner.

The goalkeeper punches clear.

More Premier League misery for Chelsea as they fail to clear from Payet's corner and Zarate drills a low shot into the bottom corner. Jose Mourinho's side have not come from behind to win a game so far this season, remember.

Goal: West Ham 1-0 Chelsea (Mauro Zarate)

Chelsea and West Ham exchanging corners but both have been defended competently. The hosts then win a free-kick as Fabregas fells Dimitri Payet and Begovic is forced to palm the Frenchman's free-kick over the crossbar.

A first chance for Chelsea as Cesc Fabregas picks out fellow Spanish international Diego Costa with a nice flick but the striker fires over the crossbar.

No early goals to speak of in the Premier League, but a sensational comeback in the Championship where Reading have conspired to blow a 2-0 lead away to Fulham and now trail 4-2 with around 10 minutes remaining. Scott Arfield has also given Burnley the bragging rights over local rivals Blackburn in the East Lancashire derby.

Each of today's five mid-afternoon kick-offs are now underway.

No alterations for Stoke either. Watford, meanwhile, hand a Premier League debut to former Napoli defender Miguel Britos. Sebastian Prodl is named as a substitute.

Just under 20 minutes until we are underway across the Premier League.

No changes for West Brom for their trip to Carrow Road, but Norwich start Ryan Bennett, Matt Jarvis and Wes Hoolahan in place of Steven Whittaker, Graham Dorrans and Martin Olsson.

Leicester boss Claudio Ranieri has restored Riyad Mahrez to the starting lineup for the visit of Palace, with Shinji Okazaki making way.

Three changes for Palace, as Adrian Mariappa deputises for the injured Pape Souare and Bakary Sako gets the nod ahead of Wilfried Zaha. Fraizer Campbell is in for Dwight Gayle, who was sent off for two bookable offences in the 3-1 defeat to West Ham last time out.

Martin Kelly lines up at left-back and there is also a welcome return to the 18 for long-serving goalkeeper Julian Speroni.

At Villa Park, Tim Sherwood makes two changes to the side beaten by Chelsea as Leandro Bacuna and Gabriel Agbonlahor come in for Ashley Westwood and Carles Gil.

Gylfi Sigurdsson, Ki Sung-Yueng and Kyle Naughton return for Swansea, with Modou Barrow, Jack Cork and Angel Rangel dropping to the bench.

As for West Ham, Chelsea loanee Victor Moses is ineligible to face his parent club and he is replaced by Mauro Zarate. Michail Antonio, a £7m deadline day signing from Nottingham Forest, is on the bench. Centre-back Winston Reid misses out with a hip problem.

Jose Mourinho has opted to field the same starting XI that drew 0-0 against Dynamo Kiev in the Champions League, with Kurt Zouma retaining his place at right-back. Goalkeeper Marco Amelia, signed as a free agent earlier this month as cover for Asmir Begovic with Thibaut Courtois sidelined, replaces Jamal Blackman on the bench. Ruben Loftus-Cheek is also named among the substitutes, with Kenedy dropping out of the matchday squad.

Fourth-place West Ham have beaten Chelsea just once in the last 18 meetings between the two sides and have not even managed to produce a solitary goal against their London rivals since second-half efforts from Carlton Cole, Mohamed Diamé and Modibo Maiga secured a 3-1 victory at Upton Park back in December 2012.

All that could well change this afternoon, however, as Slaven Bilic's confident Hammers look to continue their best ever start to a Premier League campaign and extend their unbeaten run to seven matches against a Chelsea team that beat Aston Villa last weekend but laboured to a taxing draw in Kiev on Tuesday and have already lost four top-flight fixtures this term.

That game will be our main focus this afternoon, but we will also endeavour to bring you all the goings-on from the rest of the 15:00 BST kick-offs as top-six duo Leicester and Crystal Palace meet at the King Power Stadium and Aston Villa's Tim Sherwood strives to save him job against struggling Garry Monk and Swansea.

Elsewhere, Norwich host West Brom and Watford face a difficult trip to Stoke.
There is no early game on the slate today, but we will have breaking team news and confirmed line-ups very shortly as well as live updates from across the division. Stay tuned...
