Romelu Lukaku
The jury is still out on the sale of Romelu Lukaku and it may prove to be a fine piece of business if the Belgian isn’t able to continue improving but, whilst the Blues undoubtedly received a superb fee for the player, Lukaku has the raw attributes to become the best centre forward on the planet. The signing of Diego Costa has certainly helped to soften the blow for any Chelsea fans concerned by the sale of Lukaku, but the Spaniard has notoriously dodgy hamstrings and, if he does spend a period on the sidelines, Chelsea may wish that they had Lukaku still at their disposal.
