Team news ahead of Saturday lunchtime's Premier League clash between Arsenal and Chelsea at Emirates Stadium (kick-off 12:45pm).

Arsenal will have midfielders Abou Diaby and Francis Coquelin back from hamstring injuries.

Defender Laurent Koscielny returns from a two-game suspension, but on-loan midfielder Yossi Benayoun is ineligible against his parent club.

Mikel Arteta will not recover from the ankle injury sustained against Wigan in time to feature again this season, while England midfielder Jack Wilshere (ankle) has already been ruled out along with German centre-back Per Mertesacker (ankle).

Didier Drogba will miss out for Chelsea.

The striker picked up a knee injury in Wednesday night's Champions League semi-final first-leg win over Barcelona and will be reassessed ahead of Tuesday's second leg. Fernando Torres or Salomon Kalou could get a start.

David Luiz is out with a hamstring injury, while Branislav Ivanovic serves the second match of his domestic three-game ban so Jose Bosingwa is expected to start.
