Birmingham City midfielder Bellingham has already made his mind up over where he wants to play next, according to Sport Bild.
The German newspaper state he has already rejected Bayern Munich in favour of their Bundesliga rivals - and that will come as a major blow to United officials.
The precocious 16-year-old midfielder was given permission by Blues to visit some of the clubs furiously jostling for his signature, and there were rumours he even missed a first-team game to go to Germany.
Bellingham was pictured in the back of a car driven by his father coming out of United's training ground a day after the club's 2-0 Premier League home win over Manchester City.
It was later reported the whole Bellingham family received a tour of the facilities and even met legendary ex-Red Devils manager Sir Alex Ferguson as part of the charm offensive.
