Celtic vs Arsenal Preview

Arsenal could be without up to four of their key players for the first-leg of their Champions League play-off game with Celtic.

Winger Theo Walcott is ruled out of the game with a back injury, whilst there are serious injury doubts over Bacary Sagna, Cesc Fabregas and Denilson.

Sagna took a knock in Saturday's 6-1 win over Everton while Denilson (groin) and Fabregas (hamstring) will also be assessed on Tuesday although Gunners boss Arsene Wenger believes the Spaniard has a better than 50-50 chance of playing.

Midfielder Abou Diaby has recovered from a groin injury but defender Johan Djourou (knee) remains on the sidelines.

Celtic have injury woes of their own with Dutch defender Glenn Loovens having limped out of Saturday's 3-1 win at Aberdeen with a knee problem and winger Shaun Maloney picking up a knock. Both will be assessed on Tuesday after training on Monday.

Gary Caldwell will return to the Hoops defence after being suspended for the trip to Pittodrie.

Celtic (from): Boruc, Hinkel, Naylor, Caldwell, Fox, O'Dea, Loovens, Scott Brown, N'Guemo, Donati, McGeady, McDonald, Samaras, Fortune, Killen, Maloney, Zaluska, Crosas, Caddis, Ferry.
