But now Napoli are also in the hunt, with rumours suggesting that they have approached United and the player to discuss a deal.
The Naples side’s sporting director Riccardo Bigon has asked to be kept up to date on the 23-year-old’s situation, and is believed to have probed to find out whether or not the goal-getter would be interested in Serie A life.
Rafa Bentiez’s side are understood to value him at around £10m, which is a figure somewhat lower than many outlets has suggested he may be worth.
Welbeck himself is believed to have grown angered at his distance from being a first-team regular at Old Trafford, which may be further increased this off-season with United eyeing a number of big name players.
Although a switch to Napoli would be a surprise one for the young forward, Napoli are hopeful that the lure of Champions League football may be enough to tempt him to take the plunge.
