Liverpool legend Robbie Fowler reckons Eden Hazard is frustrated in the system of Chelsea boss Maurizio Sarri.

Despite Hazard's outstanding form this season, Fowler believes the Belgian is upset.

Fowler said: "The one problem I can foresee is that he will eventually get frustrated at being played out on the left, in a role that isn't quite central to the team.

“It's fine now, with them winning and attacking, but if Chelsea are a bit off and they get a bit strangled or isolated up front, then you could see him wanting to shift to a more central role.

“I'm not trying to be naughty with him or Chelsea, I'm not saying any of this as a negative.

“I've been impressed with his attitude and their resolve, but it's too early to say the sun is permanently shining for Hazard just yet.

“West Ham may be a big test of that."
