Bacary Sagna admits there is no room for error against AC Milan on Tuesday.

The Italian champions head to Emirates Stadium for the second leg of their last-16 tie boasting a 4-0 aggregate lead after a dominant display at the San Siro.

But Arsenal go into the fixture on the back of four straight Premier League wins and Sagna is confident they can upset the odds.

“Of course it is possible, we just need to score goals and defend better than we did against Liverpool,” he told Arsenal Player.

“We have to be sharp everywhere on the pitch and I am sure we will score many goals. We will have great support from the fans and I know we can achieve a lot.”
