Former Manchester United and Arsenal defender Viv Anderson can't see Borussia Dortmund holding onto their best young players.
Bundesliga pundit and former Middlesbrough striker Jan-Aage Fjortoft has revealed a conversation he had with Anderson.
He told ESPN: "Viv Anderson said to me, 'but Jan, it's quite easy, young kids want to win trophies - that's why they're in the game'.
“One day they will go away, meet each other now at international break and they will say 'you're a good team, you have good talent, how many trophies have you got?'
“I think that is the danger with Dortmund, now having the best Norwegian (Erling Haaland), the best American (Gio Reyna), the two best English (Jude Bellingham and Jadon Sancho), although Sancho is not at the moment unfortunately.
“That is the main challenge for Dortmund, how long can they keep these young kids without winning trophies and the culture needs to be built up.
“It's also typical that Bayern [have] got that culture at the moment because they have that winning mentality in there."
