Is Chelsea's biggest worry this season the dipping form of Oscar?

Oscar has struggled to enjoy a full season of strong form since signing for Chelsea.

The Brazilian playmaker is a favourite at Stamford Bridge, and has been an almost ever-present in the first-team since his signing in 2012.

64 appearances in his debut season were followed by 47 in his second campaign, alongside a host of international games with Brazil. The summer of his arrival saw him turn out at the Olympics, whilst the end of that season was Confederations Cup action, and the end of last season was followed by the World Cup. Despite being just 23-years-old, Oscar continued his intense run of games at the start of this term, and has so far made 22 appearances in all competitions.

And, as expected of the playmaker, he has enjoyed an incredible season. He has four goals and seven assists in 17 Premier League games, and he has been a vital attacking component in the forward line who have been so efficient in moving the Blues to the top of the league table.

However, there have been indications in recent weeks that Oscar’s season could follow the same route as his last years with Chelsea have, with fatigue and poor form seeing him out of the side.

Despite scoring and assisting in the 2-0 victory over Newcastle last weekend, Oscar's performances have been well below his average for a number of weeks, and it is likely that the high frequency of games he has played since signing for Chelsea is once again coming to hurt him. He has yet to have an extended break since making his Blues debut, and, last season especially, the Brazilian has looked remarkably out of form from January onwards.

Considering how consistent Jose Mourinho has kept his starting XI this term, it looks likely that the Portuguese coach will continue to include Oscar as his chosen number 10 for the remainder of the season. If he struggles as he did last season, Oscar’s continuing inclusion could be the factor that costs Chelsea the Premier League title, but, should he enjoy a rejuvenation in the final third, well, there might not be any team who can stop the Blues attacking potency in the second half of this campaign.
