Chelsea manager Carlo Ancelotti says his side can beat Manchester United in the second leg of the Champions League quarter-final.
Wayne Rooney's scored the only goal for United, but despite late Blues pressure, Ancelotti's side couldn't force an equaliser.
Only two sides in the history of the Champions League have overturned a first-leg deficit away from home but the Italian boss believes the club's win over United at Old Trafford last season proves they're still in the tie.
"It is not easy, but we have to try," Ancelotti told Chelsea's official website.
"Obviously we know it will be difficult to win there. We have confidence from last year when we needed to win at Old Trafford and were able to do this.
"We hit the post in the first half, in the second Van Der Sar had a fantastic save. You cannot think against Man United you will have a lot of chances to score. We had chances, we were unlucky, but that's it and we have to look forward to the next game.
"We have a disadvantage now. Our performance tonight was good, not 100 percent but in general we played good football, had opportunities, worked hard and a clear chance to have a penalty at the end.
"Fortunately we have to play again at Old Trafford, it will not be easy but last season at the same moment we had to win there and we won the title," he added.
The former AC Milan manager also gave his backing to Fernando Torres, who is still without a goal in a Chelsea shirt since his £50 million move from Liverpool.
"We have to have confidence. He (Torres) has to have confidence and keep going and he'll score.
