Barcelona star Lionel Messi is confident they will overturn Arsenal's first-leg lead in their Champions League clash.
Messi is confident his side will prevail at the Nou Camp on March 8.
"It hurt to lose (on Wednesday) because we didn't deserve to," he said.
"In the first half we played really well for a lot of the time, moving the ball around quickly - it's a shame we didn't win.
"But we are relaxed because we know we can turn this around - we only have to overcome a one-goal deficit."
