Inter Milan coach Luciano Spalletti admits they must be at "100 per cent" against Champions League opponents Barcelona.

The Nerazzurri can virtually assure qualification for the Last 16 with a win tomorrow.

"They're the best," Spalletti acknowledged.

“It's the most difficult match in the game, and we have before us an opportunity to show that we really can compete with anyone.

“This is a match that gives you the chance to give anyone a game. In the matches after Barcelona we wanted to strengthen the concept of keeping the ball and positioning ourselves in the opponent's half of the pitch.

“We want to stay as far as possible from our own box and to do that we need to be a team.

“We need to be good in making sure our opponents don't have time to play, giving continuous pressure where all the players follow the ball.

“It takes 100 per cent to beat Barcelona, and we need to be able to do that."
