The agent of Ivan Perisic will meet with Internazionale to take a final decision over the player's future.
Manchester United are still eager to add the Croatian to their squad.
But the Nerazzurri have no intention of selling one of their best players as they want to fight for the Serie A title this year.
The 28-year-old has already featured in a number of pre-season friendlies for Luciano Spalletti's squad.
The Red Devils have reportedly made a bid of £39million to secure the services of the winger.
But Internazionale have rejected the bid as they intend to keep the player at least for one more season.
Mourinho has already signed three world class players this summer but he wants one last transfer to be completed before the end of the summer transfer window.
