Bayern Munich midfielder Owen Hargreaves insists they can still go through, despite losing 4-2 at Chelsea.
"Their goal was unlucky and then we got back into it at 1-1 and I thought we had control," he said.
"But Chelsea killed us with the long ball and got lots of flick-ons. We need a couple of goals but it's also important we defend well.
"We have a lot of great players going forward and we'll see if we can make a big game of it in Germany."
The England midfielder added: "I didn't think it was ever a 4-1 game and it was good to get the goal back.
"He (Frank Lampard) scored two great goals but from our point of view they were disappointing and could have been avoided.
"Didier Drogba caused us problems and we'll have to work out how to negate that for the second leg."
