Arsenal captain Cesc Fabregas is "90%" certain to travel to Barcelona for the hotly-anticipated Champions League match but Alex Song is out of the tie with a knee injury.
Former Barca youth player Fabregas has not played since injuring his hamstring in the victory over Stoke almost two weeks ago. His recovery is going well, though, and he now looks likely to take his place at the Nou Camp, where Arsenal will be looking to secure their quarter-final place by protecting a 2-1 lead from the first leg.
"Fabregas will have a final test today," said Wenger on Monday morning. "It is 90% he will travel and be fit. It is vital for us because he is important in the transition between attacking and defending. He is also the leader of the team so we want him there."
Holding midfielder Song, who started the first leg between the sides at the Emirates Stadium, has not been so lucky but, as expected, Jack Wilshere has recovered from slight ankle discomfort.
"Alex Song is completely out. He had a test on Sunday morning and it was negative. Wilshere will be fit.
"Everybody else who played on Saturday should be available."
