4. Filipe Luis
The Brazilian left-back came off a superb season with Atletico Madrid, winning the La Liga title and reaching the Champions League final, but then agreed to join Chelsea.
Luis followed Diego Costa in swapping Madrid for London, but sadly for the left-back, he couldn’t impress Mourinho like the striker did.
Often used as back-up to Cesar Azpilicueta, Luis has struggled for regular football and could already be in line with a shock return to Spain.
