Per Mertesacker insists Arsenal are good enough to “beat any team in the world” ahead of their Champions League clash in Monaco.
The Gunners have beaten Manchester City and Manchester United on the road this season, but face a major challenge at the Stade Louis II on Tuesday night.
Mertesacker says the defence are confident of delivering a much-improved performance from the first leg.
“[We feel] very good, very positive,” he said. “We have to cope with difficulties and criticism in our job, that is part of it, but we have a good chance to repair it.
“We want to do better and make better decisions. We did something wrong [in the first leg], but can we learn from that and put another performance in? We need another performance and obviously it is not going to be easy, but we have to show a different face.
“We have moved on and improved a lot, so that’s why we are very confident that, even away from home, we can beat any team in the world.”
