Chelsea boss Jose Mourinho admits he still needs to land a new central defender.

The Brazil international Alex is expected to end his three-year loan at PSV Eindhoven to complete his move to Chelsea, and Mourinho has also been linked with a new offer for the Bolton defender Tal Ben Haim, who is a free agent.

Asked how many newcomers might be joining Steve Sidwell, Mourinho, in Africa on a charity mission with Chelsea, said: "I think three, and it is obvious a central defender because we have problems during the season with injuries in defence. A central defender, a midfielder and a striker."
