Manchester United are trying to push through a deal for Ivan Perisic before the Croatia forward is due to fly to China with Inter Milan next Tuesday for the start of their pre-season tour.

But as United hope to welcome one new wide player, another is on the verge of departing Old Trafford with Belgium winger Adnan Januzaj expected to complete a £9.8 million move to Real Sociedad on Wednesday. It is unclear if United have a buyback option on Januzaj.

Negotiations for Perisic have been complicated by Inter’s irritation at the way United have gone about their approach for the 28-year-old but the Manchester club remain hopeful of getting a deal over the line.

United were understood to have made initial offers of around €30 million (£26.7 million) and 32 million (£28.5 million) as they sought to exploit Inter’s need to raise a similar amount to break even for the 2016/17 season under the terms of a Financial Fair Play ruling from Uefa.

But Inter refused to sell Perisic for a knockdown fee in order to raise those funds and United have instead been forced to significantly raise their offer for the player. United are believed to have made an improved third bid of about £40 million in the past week but remain at least £9 million short of Inter’s valuation.
