Chelsea's Eden Hazard has emphatically failed to build upon his tremendous form of last campaign, finding the net just twice all season and both in the FA Cup.
Such underwhelming displays have seen the club's fans call for the Belgian's sale this summer, yet the Blues appear reluctant to part ways with their prized asset.
And whilst the numbers suggest Hazard is at peak condition following a hip injury recently, manager Guus Hiddink senses something is wrong with the midfielder.

According to the Mirror, prior to Saturday's FA Cup defeat to Everton, he said: "We have this system where we measure the players when they are in physically good shape, or if they have too much work and they go into a 'fatigue zone' where the risk of injury is higher.
"Eden had this problem a few weeks ago. But now that risk is not that big anymore. So that suggests he can work on without a big risk.
"I'm old school. You have your smell, sense and experience, even if it helps to have computer analysis."
Hiddink continues to explain that all players at the club act differently to adversity.
"Eden is a bit different as a character, more introspective. He’s not really showing what he is thinking.
"It doesn’t mean he’s not involved. But sometimes you want to see more emotion and we accept it more easily. So we have to empathise a bit with him as well.
"He is committed, that’s why I defend him. But he’s also concerned a bit about delivering more."
Failing to score even once in the Premier League this season has led fans to question Hazard's ability, but Hiddink says he's starting to see glimpses of brilliance from the midfielder.
"Every now and then I see he is capable of doing beautiful and very efficient things.
"Some players have difficult times, although they are trying, and that’s what he’s doing in training."
