Belotti, 23, has been linked with a move to Old Trafford as Jose Mourinho searches for a striker to replace the injured Zlatan Ibrahimovic.

The Italy international has a clause in his contract, which runs until 2021, that means he would be allowed to leave Torino if a club outside Italy offered €100 million.

Cairo said that would be the only way in which Belotti, who scored 26 goals in Serie A last season, would sign for United this summer.

He said: "I'm not thinking about selling Belotti. Belotti is my player, we only renewed his contract recently. Our objective is to keep him.

"After that, there is a release clause that would make me obliged to sell him, providing someone came in with €100m from abroad.

"Let's see. I haven't talked to him yet because he is currently with the national team. We will see how things go, but our intention would be to keep him."

Belotti is one of a number of strikers to have been linked with United, and has also been reported to be interesting AC Milan.

But Gianluca Petrachi, Torino's sporting director, said the club had yet to receive any concrete offers.

Petrachi added: "On paper, Torino do not want to sell Belotti, but you all know how the market works.

"If a club were to come to us with a big offer, we would have to consider it. Either the big clubs come now or they don't come at all.

"It's unlikely that a big club is willing to spend €100m in August. If Milan want him, they have to pay a big price for him and, to this day, no big offers from Milan have arrived."
