Inter have so far resisted United's attempts to persuade them to part with their prized asset, despite Old Trafford officials visiting Milan to try to cut a deal.
Inter are holding out for a fee of £50m and have also introduced the possibility of taking Anthony Martial in part-exchange, which the Red Devils have dismissed out of hand.

"If I had to be picky, I would say that we could have been more aggressive in the second half and matched Bayern in that aspect but overall I am happy".
"Overall Inter played a very good game and I'm very proud of my team", said the former Roma coach.
"If my club is not able to do two players and is able to do just one, I will accept that as a outcome of the market now", Mourinho is quoted by the Daily Mail. United want two more players.
The 28-year-old Croatian global has been strongly associated with a move to Manchester United. "Having said that, if someone comes in with a very hard offer to reject, then we'll consider that, but of course, we'll need to find a valid alternative for Perisic as well". "He's a great player, he's one of ours and I want to keep him here with me, but we'll have to consider what the club and the player want to do".
"I'm young, I want and I have to play a lot".
