Beşiktaş J.K want to sign Manchester United striker #Anthony Martial on loan.
Jose Mourinho was keen on wrapping up a deal quickly so that Perisic did not have to travel and United were increasingly hopeful of finalising terms.
Another rumoured exit option for Martial has been some form of swap deal with Inter Milan involving Ivan Perisic, though early murmurs of a potential agreement have since gone quiet.
The 28-year-old star was one of the best players for his nation in the European Championships held last year.
'I can confirm Inter's interest in Anthony, ' his cousin, a Paris-based journalist, wrote on Twitter.
They have from the start made it clear that the English club would have to pay that price to get Perisic or at least offer a player in return, and have recently inquired about Martial.
Mourinho sent a thinly-veiled message to his former club by insisting United are willing to reduce their "need" to sign four players down to three.
It has been a long-running saga, with Inter refusing to let Perisic go on the cheap, but now the deal looks close to being finalised.
