Tonight in the Champions League, Arsenal take on Barcelona in the Champions League in a Last 16 second leg clash at the Nou Camp, and will have to overturn a two-goal deficit to advance.

The La Liga champions Barca lead 2-0 from the first leg. The Gunners have not reached the quarter-finals in Europe's elite tournament since 2010.

Barcelona are hoping to become the first team to retain the Champions League since the competition's inauguration in 1992.

The Gunners, however, are in the midst of a woeful run, having won only one of their last seven matches in all competitions.

Barca, meanwhile, are on a 37-match unbeaten run.

WHAT THE MANAGERS ARE SAYING

Arsene Wenger: "We want to make the impossible possible. We know we play against a very strong side, and it's important that we go there and focus and show a very good response," he said.

"We have shown that we can respond always. I think this team has a great spirit, a very strong attitude. They play at the moment with the idea that they cannot afford any [bad] result, but we can deal with that.

Luis Enrique (on Wenger): "It is not the case now with any coach. It means Wenger is a very good coach, no one doubts about that and only the chosen ones can be such a long time in one club - it is because of their good quality.

“I really don’t have a deep knowledge to assess the situation of Mr. Wenger, but every time there are more coaches out there and more competition and possibilities - the number of teams is always the same but there are more coaches."
