17:30 BST - Arsenal v Everton
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.

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.

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.

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.

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: 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.
