The Portuguese trainer has revealed he is not looking to sell his one of his star attackers and also reviewed Los Blancos' campaign ahead of their final fixture in La Liga
Paris Saint-Germain have been heavily linked with a move for the Argentina international with the French club's director, Leonardo confirming their interest in the player.
However, preparing for Los Blancos' final Liga game of the season on Sunday against Mallorca, Mourinho was keen to pour cold water on any potential deal for the striker.
"Some people seem to forget players are owned by a club. [Higuain] will not be going to Italy, England or Germany unless someone pays the €150m. We want him to continue with us because he is one of the best strikes in the world," the Portuguese told reporters at his pre-match press conference.
The former Inter trainer swiftly moved on to discuss the club's season and despite believing some players had the perfect season, Mourinho is adamant there is still some small room for improvement for Madrid.
"The season [for Madrid] is a nine [out of 10] but there are some players who have been a 10. Some cannot do anything else [to improve]. The team is a nine but some players a 10. Do not ask me who," he added.
"We've grown as a team and as a group. We wanted to play better and be stronger. We've played at a high level and we've created records. We have the most important title [La Liga] because we wont it over 11 months and 38 games.
"To reach the Champions League semi-finals was important because we've managed to play two in a row which means we're there. If you play 24 games and lose only two, it means you're at the right level.
"The Copa del Rey was the least important title for us but we respected it and fought well. Only reaching the quarters does not mean we didn't play football. Our numbers are impossible to improve. Next season we will aim to win the league again but this season's numbers will be very difficult to equal."
Mourinho has previously been reported to be keen to see Zinedine Zidane relieved of his director of football duties, something the coach later rejected, and the Portuguese concluding his press conference by discussing the former attacker's future along with that of Real Madrid Castilla trainer Alberto Toril.
"I do not know [about their futures]. They are questions for the boss. If Zizou switches roles it will be to something as a change for the better, that may be more adapted to him. Toril is doing a good job, fighting for promotion. It will would be normal to continue but I do not know," he added.
"The medical department is also something we're looking to improve. We want to try to add something to the technical staff to be stronger. If we can improve our medical department we would be delighted. We want to improve all aspects."
Victory for Madrid on Sunday would see the champions finish the season on 100 points, a feat never achieved by a team in the Primera Division.
