The Argentina international has continually been linked with a move away from the La Liga champions, and Paris Saint-Germain star Javier Pastore revealed earlier this weekend that Higuain has been in touch with him over a potential move.

Nevertheless, Mourinho has stressed that the 24-year-old is not for sale at any price.

"Higuain is staying here. He will stay at Madrid because I don't want him to go. He has an excellent contract here that runs for many more years," Mourinho told Spanish daily ABC.

"And Madrid have no intention to sell either. Even if clubs offer 40, 50 or 60 million euros, we will not sell him. My two strikers for next season will be (Karim) Benzema and Higuain."

Higuain has netted 22 goals in 34 La Liga appearances this season.

But Mourinho may have more of a fight on his hands to retain the services of goalkeeper Antonio Adan, who is behind Iker Casillas in the pecking order.

Adan has reportedly told Mourinho he is thinking of leaving the club to get more playing time.

"If Madrid is combing the market for a goalkeeper it's because Adan does not want to stay," Mourinho said.

"My job is to convince Antonio to stay and I have asked Iker to help. Adan is the second-choice keeper and if we cannot convince him to stay we'll have to find a solution."
