#2 Jerome Boateng (Bayern Munich)
The German international has won everything there is to win at Bayern Munich and he has been an integral part of Bayern's backline for a long time now. It seems like he has been ever present, but he is just 29 years old.
The former Manchester City defender is capable of playing as a centre back and a right back as well and this season he made just 19 Bundesliga appearances for the Bavarian giants.
Boetang is an experienced player and he would undoubtedly improve Chelsea's defence. The Blues are in need of a defender who can provide leadership, quality and experience and the German fits into the bill perfectly.
He would definitely be an upgrade for Gary Cahill who has been inconsistent and error-prone as well. Boateng has already publicly stated that he seeks a new challenge and believes at his age a move away from the Bundesliga can be considered.
Chelsea are likely to face competition from the likes of Liverpool, Manchester United Juventus and Napoli, who are keen on signing him.
