When a club spends north of £100million on a footballer, there's no doubt that said player is going to have a significant role to play.
When Enzo Fernandez was brought in by the club for almost £107million in the January transfer window, he was clearly going to be a crucial part of the first-team for the remainder of the season. Back then, Chelsea still had some sort of European ambition. They were still in the Champions League and a place in this season's top-four wasn't completely out of the question.
However, since Fernandez was signed – after weeks of tireless work behind the scenes to persuade former the midfielder's former employers Benfica – plenty has changed at the club. Graham Potter, the man who was in charge when the Argentine arrived at Stamford Bridge, was sacked from his role as head coach at the start of April. Bruno Saltor took charge for one game before the club announced the return of Frank Lampard on a temporary basis until the end of the season.
