Wenger: Chelsea is a ‘must win’ game.

Arsenal have lost to their main title challengers, Chelsea and Manchester United, already this year, though they have yet to face either at the Emirates Stadium.

The Frenchman said: “of course, this is a must-win game. We have mixed feelings because we came out of both games against Chelsea and Man United this season thinking we could have won and that there wasn’t a difference between the teams.
