Diego Costa – £32m – Atletico Madrid to Chelsea
GRADE: A
With goalscoring troubles in recent seasons, a proven striker was on the very top of Jose Mourinho’s list – and Costa has been just that for the Blues, delivering consistently in front of goal, netting 15 goals in 18 Premier League games.
The 26 year old has been a nightmare for defenders – not only is the Spaniard direct and powerful in from of goal – but is aggressive and physical.
Exactly what Chelsea needed after Fernando Torres’ torrid time at the club came to an end.
