Atletico Madrid centre-back Diego Godin has insisted that his side must be at their best for the second leg of their last-16 Champions League clash with AC Milan.

The Spanish outfit hold a 1-0 lead from the first leg at the San Siro, but Godin has called for focus ahead of the meeting at the Vicente Calderon on Wednesday.

"We're expecting a really tough game, just like the one we experienced in the first-leg. We're expecting the best version of Milan, because they're so used to playing in the Champions League," he told reporters at a press conference.

"They've held back players for this, with the intention of having a great game. That's why we're expecting the best of Milan and for sure, the best of Atletico."

Atletico have not yet lost in this season's Champions League.
