Inter Milan's Esteban Cambiasso believes his side are capable of defeating Manchester United at Old Trafford.
After a goalless first leg a fortnight ago, the two sides enter the game all square, with Inter knowing a score draw could see them through.
And, despite admitting the task ahead is a difficult one, Cambiasso insists Milan are strong enough to achieve their target if they play at the top of their game.
Speaking ahead of Wednesday's knockout tie, Cambiasso told skysports.com: "This is the match of the year for us and we must play at our best if we are to eliminate the European champions.
"We have been dealt a few injury problems in the last few days but we must not dwell on that.
"We must concentrate on putting in our best performance at Old Trafford. If we can win there it will be an enormous sense of achievement.
"It will not be easy," he added. "United played well at the San Siro to secure a draw.
"But they did not score. And now it is up to us to show our true quality.
"As a team, we thrive on big matches and big stadiums. Old Trafford will be no exception."
