Former Chelsea defender Frank Leboeuf believes centre-back pair John Terry and David Luiz can striker up a winning partnership at Stamford Bridge.
Injury has meant Luiz only made his first start of the season in mid-week against Bayer Leverkusen, while Terry was left out of the club's Champions League openers, meaning the pair are set to play together this season.
Luiz made an instant impact upon his move from Benfica during the January transfer window, scoring against both Manchester City and Manchester United, and after marking his comeback with another goal on Tuesday, Leboeuf hopes to see the pair flourish, starting with the trip to Old Trafford on Sunday.
"I think 'the hairy one' David Luiz will play alongside John more often than not this season because he has the strength and the pace and can be a great partner for him," Leboeuf said.
"I like Alex but he is a bit too similar to John. You have to find someone who is different, the pair must complement one another. Someone who can mark, someone who is faster than John - if I'd played alongside Laurent Blanc it would have been a problem, but Marcel Desailly with me or with him was fine."
The squad's current age has led many to believes a title tilt may be beyond Andre Villas-Boas' side this season, with the club's younger breed of Oriol Romeu and Romelu Lukaku as yet untested, but Leboeuf envisages everyone playing their part.
"Theirs is an important role," Leboeuf added. "I remember talking to John a lot and I have see on the pitch that he didn't forget what I told him! Sometimes when I've been to Chelsea he has thanked me and Marcel [Desailly] for advising him and helping him improve his game.
"If you have younger players who want to listen and learn, advising them is one of the best gifts you can give. Your time has gone and you are making room for younger players - it is only fair after football has given you a chance, you should pay it back."
