Arsenal and Tottenham Hotspur target Jadon Sancho has failed to turn up to a number of training sessions for Manchester City.
The 17-year-old winger was offered a new contract by the Citizens but he decided not to sign.
Red Bull Leipzig and Borussia Dortmund are also interested in the youngster.
He was left out of Pep Guardiola's pre-season squad earlier this month but academy stars Phil Foden and Brahim Diaz were include.
The Englishman is determined to leave the former Premier League champions in order to secure a regular first-team football place with a new club.
Spurs wanted the player to be included in the deal that saw Kyle Walker join City earlier this month.
But the Citizens refused to let the youngster go the other way.
