Borussia Dortmund will demand at least £100m for Jadon Sancho this summer, with Manchester United and Chelsea interested in bringing the winger back to the Premier League.
The forward, who turns 20 next month, has become a full England international since joining Dortmund from Manchester City in 2017.
City have the option to match any bid for Sancho as part of the agreement and means the Bundesliga side have to keep them informed if another club comes in.
