Chelsea boss Guus Hiddink is delighted with the attitude of Kurt Zouma after his knee injury setback.
Zouma was taken off on a stretcher in the second-half of Chelsea's clash with Manchester United last Sunday with a stomach-churning injury as he damaged his anterior cruciate ligament hyperextending his knee.
Hiddink said: "He was in a mood as if nothing had happened. He was very confident. He had his operation, which I think went well.
"It was severe, it was tough. He's out for months and months. It was a sporting tragedy for him, just in a period when I think he was improving all aspects of his game.
"Not being able to play with us in France (in next Tuesday's last-16 Champions League tie at Paris Saint-Germain), or to be a candidate for a place at the Euros, it's a tough time for a player in his career."
