At least that’s the ultimatum La Gazzetta Dello Sport claim the Croatia international has been handed as the Red Devils eye up a deal for him.
Starsport understands United and Inter have been in talks over a potential move to Manchester for Perisic since the end of last season.
However, those negotiations have so far not been decisive with the Serie A giants holding firm on their whopping valuation of the 28-year-old.
Reports from Italy suggest United could make a breakthrough if they’re willing to meet a revised price tag and throw Anthony Martial into the bargain.
According to La Gazzetta Dello Sport, a deal could be revived over the next few days.
Inter have apparently told Perisic and his agent that they can either negotiate with United or he’s staying put.
And La Gazzetta Dello Sport suggest Jose Mourinho could get his man in part-exchange for Martial.
The newspaper indicate Inter are demanding a fee of just over £40m (€45m) for Perisic.
And they want to take Martial on loan in return, with a loan fee between £5.4m (€6m) and £7.2m (€8m).
La Gazzetta Dello Sport indicate Inter would also like a clause included in the agreement specifying a fixed price for the permanent future transfer of Martial.
