Sergio Aguero scored a hattrick to undo Watford's hopes of an FA Cup upset

Manchester City escaped becoming the upset of the FA Cup fourth round with the side going from 2-0 down to beat Watford 4-2 while Liverpool took a clinical 2-0 win over Bournemouth in a day full of Cup action.

In the first match of the day the Reds went up against the seasiders 1-0 in the 26th minute thanks to Victor Moses with Daniel Sturridge sealing the win after 60 minutes. Luis Suarez was on fire once again for the side but unable to hit the target while Bournemouth had few chances despite holding their own against Brendan Rodgers' side.

Sturridge said after the game: "We worked hard and our quality showed.

"The runs Luis Suarez makes and the determination he has - it's easy to see his runs. Usually he's running towards the goal. He was unlucky not to score. The goalkeeper had a good game."

Suarez added: "When you play away it's a difficult game. But we knew if we win today, it's a good chance for the next phase."

Meanwhile City were placed on the backfoot early by Championship-side Watford as Fernando Forestieri put his side up 1-0 after 21 minutes. Within nine more they were 2-0 up and in a position not many would have predicted as Troy Deeney hit the left corner of the net with his brilliant shot.

In the second half City peeled one back thanks to Sergio Aguero and the Argentine went on to become the savior for the side, equalising in the 79th minute with a shot that would halt any chance of a Cup upset at the Etihad.

And due to a howler from Watford keeper Jonathan Bond City went up 3-2 with minutes to go, ending the side's dream of going through to the next round at the expense of the Premier League favourites. Just as the pain couldn't get any worse for the once celebratory sid,e Aguero scored a hattrick in the 90th minute.

Meanwhile elsewhere, Swansea took a 2-1 win over Birmingham while Cardiff are also through to the fifth round after a 1-0 victory over Bolton. Wigan left Crystal Palace behind with the Premier League newcomers unable to comeback from 2-1 down to get through to the last 16.
