Chelsea fans react on Twitter to Aston Villa defeat: "Unbelievable implosion..."

Chelsea's pursuit of the Premier League title took a hit tonight after a surprise 1-0 defeat at the hands of Aston Villa.

Fabian Delph's goal late in the second half secured the win for Villa, but Chelsea's second half implosion will be of concern to Blues fans, who witnessed both Willian and Ramires pick up red cards, leaving Chelsea with just nine men on the field by the end of the game, whilst manager Jose Mourinho also received his marching orders for protesting late on.

The Blues loss will give hope to Manchester City that they can now pile the pressure on Mourinho's side, after Manuel Pellegrini's men clinched a 2-0 win over Hull City earlier today. Chelsea remain top of the Premier League table, but sit just six points ahead of City - who have three games in hand on the West London club.

It was a below par display from many Chelsea players, but much of the blame for the defeat fell at the feet of referee Chris Foy, who dismissed two Chelsea players and the manager - adding to a theory that Foy regularly sends players off whenever he is refereeing Chelsea games.

But aside from Foy, a number of players took criticism for their displays on the night, including Ramires, Branislav Ivanovic and Nemanja Matic, whilst some fans called for the inclusion of January signing Mohamed Salah on a night where Chelsea were shocked by Paul Lambert's side.
