Manchester City have control of Jadon Sancho's future at Borussia Dortmund.
City sold the 18-year-old winger to Borussia Dortmund for around £8million in the summer of 2017, after the Londoner decided against signing a lucrative new deal.
The Blues had offered him the biggest deal in the history of their academy - said to be around £30,000 a week - but when he insisted on a move, they made it plain they would not sell to a Premier League rival.
Dortmund have moved to protect their asset by tying him up with a new contract until 2022 and, if he does move, City are believed to have a 15 per cent sell-on clause, says the Manchester Evening News.
If they want to take him back to the Etihad Stadium, they had a buy-back clause inserted in the contract which saw him move to Dortmund.
That means if City match any fee offered for Sancho, they will get first refusal.
