The Inter coach would prefer to keep the Croatia international, who has been heavily linked with a summer move to the Premier League
Inter will only sell Ivan Perisic to Manchester United if a significant transfer fee is offered, head coach Luciano Spalletti has warned.
The Croatia international has been linked with a move to Old Trafford for a number of weeks but no agreement has yet been reached over a deal.
United boss Jose Mourinho admitted last week that he had "no idea" if Perisic would join the club and the winger has been involved in Inter's pre-season plans, starting the 1-1 friendly draw with Schalke on Friday.
