Chelsea manager Jose Mourinho has warned that "selfish" players will be in "big trouble" during his spell at the club.
The Portuguese, who returned to Stamford Bridge this summer after leaving Real Madrid, is hoping to guide the Blues back to the top of the Premier League table.
To do that though, the coach says that he will first make sure that his team are ready to give 100 percent for the cause.
"There is something I say at every club I go to, and I’m going to say it again when I meet the players on July 10,” he told reporters.
“It’s a sentence that I always say on the first day: If you are a top professional, if you are not a selfish person, if you put the club in front of yourself, and if you are here to work 100 per cent for me, for your fellow players and for the club, we will have a wonderful relationship.
“If you are selfish, if you don’t care about the fans, then we are in big trouble.”
He continued: "Sometimes you have a couple of guys that are not too keen to accept these kind of rules and this is where you have some problematic relationships, and the club in that moment either supports the problematic player or the manager.
“If the clubs support the manager, the two little guys — gone, easy.”
