It was one of the most well-documented transfer stories of the summer.
And now, Manchester United target Ivan Perisic looks to be out of their reach for good.
The Croatian has made a good start to the season with Inter Milan having missed out on a move to Old Trafford, scoring in their 3-0 opening day win over Fiorentina.
United refused to pay more than £39m for the winger in the summer, and Inter wouldn't settle for anything less than £49m.
Perisic is set to sign a new deal at the Italian giants - though a clause in the deal means the Red Devils will be powerless if they attempt to sign him again.
Italian publication Gazzetta Dello Sport say that the deal will include a release clause that excludes foreign clubs.
Dubbed the 'anti-Manchester United' clause, it means that Inter will be able to command a huge fee from other European teams for the former Wolfsburg man.
Perisic will reportedly be earning £4.1m per year, and the contract ties him down at the San Siro until 2022.
However, there is no specific number quoted for the release clause.
It means United have suffered a huge blow if they try to return to land one of their top targets from the summer, though Anthony Martial, Henrikh Mkhitaryan and Marcus Rashford have started the season in sparkling from on the wings.
Mourinho admitted defeat in their battle to sign the Croatian at the start of August, and praised his former team with their resilience in negotiations.
"That’s football", he said.
"If I was playing against Inter tomorrow I’d want to win.
"They’re strong, they put up a good defence to keep someone who’s an important player for them. That’s football."
