Jude Bellingham's move to Borussia Dortmund has stalled, according to reports.
The Birmingham City midfielder, 16, agreed personal terms with the Bundesliga club.
However, Sport Bild says the two clubs cannot agree upon a fee.
The news opens the door for Manchester United to try and secure Bellingham's signature.
The Englishman toured United's Carrington training facility earlier this year and remains tempted to join the Red Devils.
