Much has been made of Chelsea's transfer spending since the arrival of Todd Boehly and Clearlake Capital - understandably so given £600million in expenditure has only helped to land the Blues with a bottom half finish.
Few moves have hit the ground running but many have been made with an eye on the future, and will have a chance to prove their worth under the next manager and beyond.
Noni Madueke, David Datro Fofana, Benoit Badiashile, Andrey Santos and Malo Gusto are all 21 or younger and signed in January, while the Blues invested in their development squad over the summer to add the likes of Zak Sturge, Gabriel Slonina, Omari Hutchinson and Cesare Casadei in addition to Carney Chukwuemeka, who more quickly gained first-team involvement.
