Benfica defender Luisao has dismissed Champions League opponents Chelsea.

The Brazilian defender is looking forward to stopping Didier Drogba in their Champions League quarter-final - and facing his international pal Ramires.

Luisao, 31, said: "I can't see how Chelsea start as favourites.

"We knocked United out of the Champions League and we can do the same to them. The key will be the first leg in Lisbon. If we can get a result there we should be able to manage them in the second leg.

"Chelsea are not as good as they have been in the past, although they had a great win over Napoli. To stop Drogba or Torres is easy, but always a great challenge. And it will be great to play against Ramires."
