Patrice Evra says it would be "catastrophic" if Manchester United fail to progress to the quarter-finals of the Champions League.

The Red Devils entertain the French champions at Old Trafford on Tuesday night in the second leg of their last-16 clash.

Sir Alex Ferguson's side claimed a 1-1 draw in the first leg at Stade de Gerland courtesy of Carlos Tevez's late goal and Evra is now looking to see off Lyon in the reverse fixture.

United are set to make a number of changes, with the likes of Cristiano Ronaldo and Wayne Rooney handed a rest against Fulham at the weekend, and Evra knows everyone will need to be at their best to progress.

He said: "If we go out of the Champions League on Tuesday it would be a massive blow for the club - it would be catastrophic.

"I have a big respect for Lyon because they are a good team. As a Frenchman, I am fully aware of their qualities.

"They played very well in the first game and we had to work very hard for a draw. But we are Manchester United and that means we simply have to go through.

"We know we can beat everybody at Old Trafford. On European nights, Old Trafford is a very special place when the crowd gets behind us.

"We have got our full squad together now and we'll need everyone to be at their best to make sure we beat Lyon."
