Former Chelsea midfielder Michael Ballack believes Diego Costa should turn down a move to the Chinese Super League and remain at the club because he is already earning more than he can "spend in your lifetime."
According to the Mirror's John Cross, Ballack discussed the riches on offer from China:
It's crazy. It's numbers that we are not used to, even if in England there has been a lot of money involved for a while. It's still another level.
I don't think it's normal, but hopefully we come back a bit to normal days and players remember they are playing in the best league in the world.
