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 England forward Theo Walcott is still out with a back complaint and defender Johan Djourou (knee) remains on the sidelines.
Arsenal (from): Almunia, Sagna, Vermaelen, Gallas, Clichy, Eboue, Song, Diaby, Fabregas, Arshavin, van Persie, Eduardo, Mannone, Bendtner, Denilson, Ramsey, Wilshere, Gibbs, Silvestre.
