ARSENAL VS CHELSEA TEAM NEWS; COSTA STARTS, HAZARD BENCHED........

MESUT OZIL AND DIEGO COSTA START FOR ARSENAL AND CHELSEA RESPECTIVELY WHILE HAZARD AND SANCHEZ ARE ON THE BENCH.

The striker, who has five goals in his last six games, will feature from the off despite a lack of training, with Arsene Wenger positive on the German's fitness earlier in the week

The Spain international forward was withdrawn prematurely from last weekend's draw with Everton due to a knock, has not trained significantly this week but is named in Guus Hiddink's starting line-up.

Eden Hazard also makes a return, being named in a matchday squad for the first time since picking up a groin injury against Crystal Palace on January 3.

Meanwhile, Arsene Wenger revealed earlier in the week that Ozil and Alexis Sanchez were available for the game at the Emirates Stadium, with the World Cup winner starting and the Chilean on the bench.

The Premier League leaders have been without Sanchez since late November owing to a hamstring problem, while Ozil missed last week's 0-0 draw at Stoke City with a foot inflammation and illness.
