Arsenal's Alexis Sanchez and Manchester United's Henrikh Mkhitaryan are close to swapping clubs, in what would be excellent business for both parties.
The 29-year-old Chilean forward was a top target for Manchester City - but Pep Guardiola has dropped out the race after United offered him more money.
Sanchez has reportedly agreed personal terms to join Jose Mourinho in Manchester but the deal hinges on Mkhitaryan going in the other direction.
The Armenian midfielder was not included in United's matchday squad for Monday night's 3-0 Premier League win over Stoke City.
"I would lie if I said it was a pure tactical decision [to leave out Mkhitaryan]," Mourinho told Sky Sports. "It was just a choice of the players that we know, in this moment, they have 100 per cent their heads in Manchester United.
"He [Mkhitaryan] is a player that I like, of high quality. Is he going to be involved in one deal in leaving us? It's possible. But it's also possible that he stays.
"The market is open."
Mkhitaryan makes two demands to sign for Arsenal
According to The Mirror, Mkhitaryan’s agent Mino Raiola has laid out some important demands if Arsene Wenger is to secure his signature.
The 28-year-old Armenian midfielder is currently on £150,000-a-week at United but - despite falling down the pecking order under Mourinho - wants a pay rise in order to leave Old Trafford.
Arsenal, who are renowned for being thrifty under Wenger, have also been told to stump up a big agent fee of more than £5m to land the former Borussia Dortmund star.
“Sanchez is part of Mkhi’s deal," said Raiola on the speculation. "Not the other way around. Without him, Sanchez simply cannot go to United.
“Mkhi’s problems at Man Utd are purely related to playing football. He has no problem with the manager. It is not personal. And he has two and a half years left on his contract. He doesn’t have to leave.”
Arsenal are reportedly expecting Sanchez to join Man United - whether or not Mkhitaryan is part of the deal.
The Gunners believe that Raiola is just playing hard-ball in order to get his client the best possible deal.
