Chelsea manager Guus Hiddink has charged attacker, Eden Hazard to improve his fitness levels if he is to regain his form.
The Belgium international was on a high last season, but has endured a sombre season so far.
And Hazard could not even last for a full 90 minutes in the last 16 tie against PSG.
But Hiddink is looking for more from his playmaker.
“He was a threat going forward and he had some good runs, but of course, this was a game with a high intensity. After 65, 70 minutes, it was enough for him,” the Dutchman told Sky.
“He has to grow and when he does, his shape will grow as well. Happily we also have Oscar for his position. He will get better and better.”
Although Hazard has played in nine of Hiddink’s 12 matches in charge – he missed three due to injury – Tuesday’s was only his fourth start.
