Emre Can has claimed that he cannot see a logical reason for Jadon Sancho to favour Manchester United over Borussia Dortmund.
Having starred for the Bundesliga outfit this season, Sancho is being tipped to make the switch to Old Trafford during the next transfer window.
Numerous reports have indicated that the England international regards United as his preferred destination, despite his links with Manchester City.
However, Can, formerly of Liverpool, has questioned why the 20-year-old would want to leave the Westfalenstadion.
Speaking to Bild, Can said: "I see no reason to put Manchester United above Borussia Dortmund. Not from a sporting side and not because of the appeal. I'd tell him to stay put and let's play together forever.
"Jadon has class that not a lot of players possess. I noticed that fairly quickly. He's enormously important for us."
Sancho has just over just two years left on his contract, putting Dortmund in a position where they may begin considering offers for the attacker.
