Jose Mourinho has praised Loic Remy for his commitment in training while often being left on the Chelsea bench behind Diego Costa this season.
The striker is likely to start against his old club when the league leaders go to Queens Park Rangers this weekend, with Costa sidelined with a hamstring injury.
The manager told the club's website: "Even week after week when he was on the bench and Diego was starting matches, he pushed himself always to the limits to be in condition to answer when the right moment arrived.
"Some players when they are not playing, the level of focus and commitment and training goes down, so after that when the team needs them they are not there for the team. Remy is a professional with a great profile, every time working very hard and when he was playing, whether scoring or not scoring, he was always there for the team.
"Now he has scored two goals in two matches and he makes some important points. I like him because he can score goals and that is important for a striker, but at the same time, his movement is always good and when the team is not in possession, he knows it is better when the team defends with 10 players and he has that contribution."
Remy has scored seven goals in 24 appearances in all competitions for Chelsea so far this season.
