Cesc Fabregas and William Gallas have been named in the Arsenal team to face Barcelona.
The Arsenal captain was given a 40 per cent chance of playing after picking up a leg injury at Birmingham on Saturday. But he will start against his former club provided he feels no ill-effects during the warm-up.
Gallas has not played since the 1-0 win over Liverpool in February, missing eight games with a calf injury. He returns to partner Thomas Vermaelen at the heart of Arsenal's defence.
Meanwhile, Arsenal legend Thierry Henry has been named on the bench for Barcelona.
Arsenal team: Almunia, Sagna, Gallas, Vermaelen, Clichy, Song, Fabregas, Diaby, Nasri, Arshavin, Bendtner. Subs: Fabianski, Rosicky, Eduardo, Walcott, Denilson, Eboue, Campbell.Copyright 2015 The Arsenal Football Club plc.
