Chelsea vs Arsenal head to head: Cesc Fabregas, Alexis Sanchez, Diego Costa and more - the title derby in numbers

Premier League leaders Chelsea host Arsenal on Saturday, with the Gunners' title hopes on the line at Stamford Bridge.

Antonio Conte's Blues dropped two points with a 1-1 draw against Liverpool at Anfield on Tuesday night, but Arsenal's shock 2-1 home defeat to Watford - coupled with Tottenham's Sunderland stalemate - meant Chelsea extended their lead at the top of the table to nine points.

Chelsea increase take their advantage on Arsenal to 12 points with a win in Saturday's early kick-off, and the Gunners are up against it with midfield injury problems mounting and Arsene Wenger set to sit among Chelsea's fans as he serves his touchline ban.

While a win would by no means seal the title for Chelsea as early as February, a victory for Arsenal would give the Gunners - and the rest of the chasing pack - hope that Conte's men can be caught.
