Once that happens, both Inter and the player will make a careful evaluation."The Red Devils have also been linked with moves for goalkeepers David Raya, Roberto Sanchez and Diogo Costa.Inter Milan unlikely to stop Andre Onana from joining Manchester UnitedSky Italia journalist Riccardo Gentile has suggested that Manchester United are highly likely to sign Andre Onana this summer. He claims that Inter Milan are aware that they can raise good money from the goalkeeper, whom they signed on a free from Ajax.He was quoted by FCInter1908 as saying:"Inter are doing well. The Onana operation is a good signal, the ability to go and get him for free and resell it at that figure, is a crazy market operation. If an offer like that comes you can't say no to make ends meet, that's how it works."The Red Devils are in the market for a goalkeeper as David de Gea's contract has run down and there is little clarity over his future at the club. The Athletic have reported that he had agreed on a new deal earlier in the year, but the club backed out of the agreement as they wanted to further lower his wages.
