Sir Alex Ferguson's side take a 3-2 lead into Wednesday's second leg at the San Siro and Kaka insists his side are focused on reaching the Champions League final in Athens.

"I want to do everything so the team can finish as high as it can. We really want to reach the final," the 25-year-old Brazilian told Milan Channel.

"They (the fans) will be crucial. They have been every time we played at home. Our fans have been behind us in this difficult season and they won't let us down in the next game."

Kaka earned the plaudits at Old Trafford with two well-taken goals and he believes he is hitting top form at a crucial time.

He said: "The thing that most pleased me is that we can win the next game - that gives us confidence. I have received so many compliments but the thing to do is to think of the decisive game.

"I feel good and I am in form at the right time."

Gennaro Gattuso could miss the second leg after limping off at Old Trafford with a foot injury and Kaka is hoping the combative midfielder will recover in time.

"Foot problems like that are not easy to get over - it's painful but I really hope 'Rino' will be there," he added.
