Diego Costa

Costa signs for the English side for £32 million from Atletico Madrid. He will play the role of striker and his squad number is 19. He signs a five-year contract with the Blues and he settles for £250,000 a week which makes him one of the highest paid in the Premier League. Mourinho:

I always thought that Diego and Cesc would bring us to the dimension we want because they are different players to what we had in the past.
