Chelsea have been linked with Raheem Sterling, who says he is not ready to sign a new deal with Liverpool.
According to Mourinho, if a player does not want to work with him, he will let him leave only if the fee is right.
“I don’t like players that don’t want to play for me and my club. My opinion is every player has a price,” Mourinho said.
“It doesn’t matter which player. Every player has a price. If you ask me now, for example, Eden Hazard, we can speak about him because he’s signed a new contract.
“Do I want him to leave Chelsea? No. If he wants to leave and doesn’t want to work with me, doesn’t want to play for Chelsea, does Eden Hazard have a price? I think he has a price.
“He’s the best player in the Premier League, but I could talk about a normal player, too – every player has a price.
“But I also understand the philosophy of managers and clubs who want to keep players at any price, who want just to say, ‘There is no price to sell. The player stays, whatever [happens].’ It’s also a philosophy I accept.
“If a player has a contract, the club, the manager and the board have the power to decide what to do, and I’d never criticise people who think differently.
“If a player knocks on my door tomorrow and says he wants to leave, doesn’t want to work with me, I’d say to my board, ‘Let’s see what our value for the player is.’
“I always think that the player’s value is decided by the selling club. Not the agent, the player, the player’s father, not the cousin – the club.”
