The contract wrangle surrounding Bundesliga prodigy Jonathan Tah has alerted five elite Premier League clubs, according to the Daily Mail.
Arsenal, Manchester City, Chelsea, Liverpool and Manchester United, who between them make up five of the top seven teams in the Premier League table, are all watching the player's situation closely.
Tah, who turns 18 next week, recently signed a new lucrative deal with Bundesliga outfit Hamburg to keep him at the club for the next four-and-a-half years - a two year extension to a three year deal signed last January.
However, Fifa rules dictate that a player under the age of 18 cannot be tied down to a contract of more than three years. Any contract that breaks the rule will not be recognised by Fifa.
His father Aquilas is currently pursuing legal action in an attempt to void the deal that contains a £20.7m release clause.
All five of the Premier League clubs are in need of defensive reinforcements in the summer and the Germany under-17 captain fits the bill for all of them.
Arsenal currently have just three centre-backs in their ranks and one of them, Thomas Vermaelen, has struggled for form and fitness over the last 12 months. Arsene Wenger will need to add to his defence in the summer, especially if rumours linking the Gunners captain with an exit are true.
Similarly, David Moyes is facing up to the prospect of his captain and centre-back departing Old Trafford. Nemanja Vidic is out of contract in the summer and reinforcements will be needed if he doesn't renew.
Manchester City, who are believed to be pursuing their interest the most, are rumoured to be keen to offload Joleon Lescott and sign a younger, more long-term option. Tah is seen as the perfect replacement for the Citizens.
Chelsea, meanwhile, have just purchased Kurt Zouma from St Etienne but must continue to rebuild as John Terry and David Luiz continue to be linked with moves away from Stamford Bridge.
Finally, Liverpool are set to offload injury-prone Sebastien Coates in a loan deal. The Uruguayan has no place in Brendan Rodger's plans at Anfield and is expected to depart permanently in the summer.
