Barcelona will still be strong on Tuesday night according to Arsène Wenger, despite being without three key players.
Centre-back duo Carlos Puyol and Gerald Pique are both suspended while Zlatan Ibrahimovic is injured.
However, Wenger does not believe that will make Arsenal's task any easier in the Champions League Quarter-Final second leg.
"I don’t think they have any reason to speculate on any weakness when you look at the opportunities and possibilities they have to get over the suspensions," he said.
"They have plenty of opportunities, plenty of centre-backs still available. I believe it is more important to focus on our side and how well we want to play."
Ibrahimovic sustained a calf injury during the warm-up ahead of Barcelona's 4-1 win over Athletic Bilbao on Saturday and has been ruled out of Tuesday's match.
That could mean Thierry Henry plays a larger part in the second leg than he did in last week's 2-2 draw at Emirates Stadium.
However, having seen their win over Bilbao, Wenger is not expecting to see his former striker start at the Nou Camp.
"It can happen," he admitted. "But it doesn’t look at the moment that they go for this solution because in their last game they played Bojan so I am not completely sure they will go for Thierry.
"But it could happen that he plays against us tomorrow night. You could have Campbell v Henry again - that I have seen so many times in training sessions."Copyright 2015 The Arsenal Football Club plc.
