Manchester United boss Sir Alex Ferguson believes Carlo Ancelotti is frustrated after Chelsea failed to sign Kaka in the summer.
Chelsea chased hard for the AC Milan star, before he chose to join Real Madrid.
Ferguson said: "At Chelsea he hasn't got a Kaka-type figure. That's why they are still looking for a player who can play in that forward role to balance the team.
"They've tried Lampard and Deco and even Malouda. Now he's looking at Joe Cole.
"Chelsea aren't the finished article at the moment, but they have the experience that will help them cope with it."
