Will Wenger drop the out of form Ozil?
GK) Wojciech Szczesny
The Polish stopper was sent off against Bayern in the Champions league midweek, so will be suspended for the next leg. He will however be available for the Premier League trip to Sunderland.
DR) Bacary Sagna
The Frenchman is almost certainly leaving at the end of the season when his contract, but is still an automatic starter when fit. Arsene Wenger will have a difficult job replacing him in the summer.
DC) Laurent Koscielny
With Thomas Vermaelen injured, Wenger has no choice but to start his regular pairing of Koscielny and Mertesacker.
DC) Per Mertesacker
The giant German defended well against Bayern, and put in a typically resolute performance. He will be hoping for an easier afternoon against the Black Cats.
DL) Nacho Monreal
Kieran Gibbs came off injured midweek, so Spanish left-back Monreal will almost definitely come in to the side in his place.
