Manchester United manager Sir Alex Ferguson believes his side will have to adapt their game to cope with our physical power, and admitted his side lack the experience of the Blues.

Ferguson, a Champions League winner in 1999, saw his side beaten 1-0 at Wembley in the FA Cup Final last season thanks to a Didier Drogba goal in extra-time, and he is sure that the Ivorian is just one of a number of Blues his side will need to keep an eye on.

'I think tactics will come into it. I think Chelsea are physically a stronger team than most of the Premier Division teams anyway and base a lot of it on playing to that strength,' he began.

'There's no point trying to match that, we have to play to our own strength with the movement and passing ability to create openings in the game. I think we're good at that so I don't want us to change too much, but we have to pay attention to the strengths of Chelsea, no question.

'We have to pay attention to the strength of Drogba, and players like Ballack and Lampard who are big strong lads. If we don't we won't win the game, and part of our preparation has been about that.'

United boast five previous Champions League winners among their number, with goalkeeper Edwin van der Sar, defenders Gary Neville and Wes Brown and midfielders Owen Hargreaves and Ryan Giggs all having lifted the European Cup in the past.

Despite this, Ferguson recognises a lack of big-match experience in his camp when compared to Chelsea, and that finding a winner could hinge on substitutions.

'We don't have the overall experience of Chelsea in terms of age and the players they have, but they've got the nerve, the courage and I think that will make some difference tomorrow.

'I think we are fresher with the 10 day preparation, and that applies to Chelsea also. In last year's Final we were at the point of having played so many games with the same 11, 12 players really. We had no real reserve to change the game, this year we have.

'Sometimes the game is won by your subs and I feel we are in a strong position as opposed to last year.'

Indeed Ferguson can rest on the experience of Barcelona in 1999 to support that view, when substitutes Teddy Sheringham and Ole Gunnar Solskjaer came off the bench to fire them to victory over Bayern Munich.

Experience though is not something he believes is necessarily an advantage when it comes to management, and he expressed his view that Avram Grant has no need for nerves in what is the biggest game of his career to date.

'This is my fourth European final (one Cup Winners' Cup with Aberdeen, one with Manchester United and two Champions League Finals) so the one person who shouldn't be nervous is myself. I think that I have to use my experience and composure to help everyone else.

'I think when I went to my first final against Real Mdarid, I didn't shrivel, I went up and had my bottle of whiskey and thanked them for being there with us. It's an opportunity for Avram Grant the same as an opportunity for me. It's a one off thing. You have to relish the moment and don't miss it.'
