The 34-year-old has appeared to be on his way out of Chelsea for some time but he agreed a contract extension last May until the end of this season. When called upon the French striker seems to deliver and he could reportedly put pen to paper on a new deal.
"If you see him on a daily basis, you can't be surprised. His body is in shape, his physicality is top level. He enjoys every day being a professional soccer player. He trains like a 24-year-old," he said.
"He is the guy who has a good mix of being serious and enjoying training.
"He is always positive and a big factor for the group. When he starts or comes off the bench, he has all the qualities."
