Jose Mourinho will always be part of the Chelsea story after delivering the club's first title in 50 years, but the nature of his sacking after his second spell in charge has left him open for criticism, including his decisions over transfer policy.
Chelsea signed Kevin De Bruyne and Romelu Lukaku for modest sums and sold them on for a profit. The pair have gone on to take their games to the next level with De Bruyne being regarded as one of the top talents in English football while the Blues tried to resign Lukaku in the summer.
