Guus Hiddink insisted any decisions over the Eden Hazard's future were not his to make, but he envisages Chelsea's talisman will soon rediscover his form

The Belgian is arguably the Blues' leading player and the 25-year-old is set to start for the first time in four weeks at stadium:mk following a groin injury.

Hazard last year signed a five-and-a-half year contract extension, but his future has been subject to conjecture after an indifferent season without a club goal.

"It's up the club, but he's a very important player," Hiddink said. "When he gets his rhythm back - and I hope fully in the upcoming weeks - then he's of big value to Chelsea. He is eager to perform, but the physical fitness must be there."

Hazard last season was valued at £200m by Mourinho and compared with Lionel Messi and Cristiano Ronaldo, but the consistency of performance still appears to be lacking and he has flattered to deceive on several occasions this season.

Hiddink said: "He's young. He has three, four, five years still to come. He has proved he can be one of the biggest.

"For the club, beautiful times can come up from him, and on top of that there is a Euros coming up. It's a beautiful period."

Elsewhere, Radamel Falcao has one goal for Chelsea this term and has been out since October with a thigh problem.

Hiddink wants the former Colombia striker, who is on loan from Monaco, to give him a selection dilemma once he returns to fitness, following the arrival of Alexandre Pato.

"We have to help him to get back to what he once was - as a striker who scores lots of goals," Hiddink added.

"Hopefully I will have problems to pick my striker, or the second striker, or third striker, or who I put in the stands for the game. I hope to have that problem as soon as possible."
