1) Didier Drogba
It is never easy to say goodbye, although Drogba has experience in this field, having left the club in 2012, soon after winning the Champions League final for Chelsea with the decisive penalty in a shoot-out against Bayern Munich.
All the evidence suggests it is definitely time to hit the road again. His presence in the dressing room is important to Mourinho, but the 37-year-old has not scored since December 6 and he is playing second fiddle to hitman Diego Costa these days. An ambassadorial role possibly beckons.
