Carlo Ancelotti believes Chelsea's superior "strength and power" can help them beat Barcelona to this season's Champions League title.
Barca are hot favourites to land their fourth European Cup, with some observers even dubbing them the best club team of all time.
Chelsea may well need to defeat them if they are to realise their own Champions League dream and manager Ancelotti is adamant the Catalan giants are are not invincible.
"Barcelona now are the best team in Europe," said the Italian, whose side will join Barca in this season's quarter-finals barring a massive shock in their last-16 second leg against FC Copenhagen on Wednesday night.
"The performances of Barcelona at this moment are fantastic, but every game is a different story.
"If we have to play them, we have to try to find a solution to beat them."
