Manchester United fullback Patrice Evra is confident they can knock off Inter Milan in the second-leg of their Champions League tie.
"It's a little bit frustrating because we had a lot opportunities to score, particularly in the first half," said Evra.
"But overall we played very well.
"Now we are at home and we have to win, and I think we have the power to do that."
The France international added: "We have had a lot of injuries problems in defence recently but we have still looked strong in every game.
"The Inter game is another example of that - we were without Vidic who is a very important defender for us, but Jonny Evans came in and played very well.
"I am really pleased for him because he's a top quality defender."
