5 players who have underperformed for Chelsea this season 

#3 Gary Cahill

Cahill in front of the Chelsea faithful

Chelsea captain and England international Gary Cahill is a two-time Premier League winner and a Champions League winner. The Englishman is a highly experienced, strong defender who has struggled to find his feet so far this season.

Having made 10 appearances for the Blues this season, Cahill has been part of the team that racked up four clean sheets. However, the England vice-captain still needs to improve and step up his game. To lead the club, from the back, on the field and help and it's young and new players, Cahill will have to get used to the captaincy role.

With his contract running out in 2019, the England defender will need to put in a string of great displays this season in order to ensure his future at the club and possibly look to extend his stay. Cahill began the season with a red card, was slapped with a three-game ban and has found it hard to cement his place in the starting eleven post the incident.

The central defender adds great solidarity to the backline and is a veteran challenger in the race for the Premier League crown.
