The Portuguese boss has allegedly agreed to personal terms ahead of a move to Old Trafford this summer as he looks to join Benfica defender Victor Lindelof.
A move for Real Madrid forward Alvaro Morata is also expected to be completed this week as Mourinho looks set to get the Premier League club’s highest-priority business done by the start of July
Lindelof signed for a fee of around £31m, while Real are holding out for £78m on Morata and Internazionale hopeful of £50m for Perisic.
Both players are said to be keen on a move to United and it’s working well for them so far, however, there are other clubs also interested in a potential deal so they must act fast.
Inter also face pressure as they need to bring in £26m before the end of June to comply with Financial Fair Play regulations.
It’s a great start so far and Mourinho has proven his intent to sing players that he believes will turn the squad into contenders in the Champions League and Premier League.
