Arsenal suffer fresh injury blow for Chelsea clash

Arsenal have suffered a fresh injury blow ahead of the Premier League derby against Chelsea on the road on Sunday.

The Gunners registered an impressive 3-1 win over Bayern Munich in the Champions League on Wednesday night.

They will be aiming to carry the momentum into the London derby, but will have to cope with another key absentee.

Leandro Trossard was substituted early in the game with a knock and that will keep him sidelined against the Blues.

Manager Mikel Arteta did not reveal the extent, but it is reportedly concerning enough for Trossard to miss Sunday's game.

Trossard has started each of the previous eight league matches and the streak looks to set to end after an untimely setback.

In his absence, one of Gabriel Martinelli or Noni Madueke could start on the left side of the attack for the Gunners.

Martinelli looks more likely to get the nod over Madueke, given he is a specialist in the role unlike the Englishman.
