Mason Mount has struggled to reach the same heights he reached last season, but his overriding impact at Chelsea has been awe-inspiring. Since breaking through under Frank Lampard, the 23-year-old has been central to much of the Blues' success, evolving into the side's primary catalyst.
The Cobham graduate has etched himself into Chelsea's starting eleven, regardless of the boss, averaging 72.7 minutes a game across 148 appearances. Mount frequently steps up in the big games for the west London side, directly contributing towards goals in crucial Champions League knockout round ties and clashes against Premier League title rivals.
Thomas Tuchel has admitted to the winning 'aura' that the midfielder brings to the table, making him an undroppable feature of the starting eleven for both club and country. Earlier this season, with Mount in the starting lineup, the Blues' enjoyed an 89 per cent win rate, but without him, it was just 46 per cent.
