Well im not a fan of Chelseaand thers not much you can improve, but heres what I would do:
1. Buy a proper DR - Dani Alves
2. ?
I dont really know mate
Maybe sell someone and change the system to a 4-3-3 and get yourself a world class right winger.
Cech
Alves-Terry-Carvalho-Cole
Essien
Ballack-Lampard
Ribery Robben
Drogba |
