Jadon Sancho looks set to be one of the names of the summer transfer window, as the player has been tipped for a big-money move to the Premier League.
The Borussia Dortmund player has been courted by the likes of Chelsea, Liverpool and Manchester United.
Sancho has scored 7 goals and provided 17 assists in 35 games for the Bundesliga side.
The star would cost between £100million and £130million.
Sancho has previously spoken of his admiration for Chelsea boss Frank Lampard and it could give the Blues a slight advantage.
Speaking ahead of Dortmund's Champions League exit at the hands of Paris Saint-Germain, Watzke told RMC Sport: "Jadon is a great, great talent, maybe the greatest talent in Europe currently of players under the age of 21. In my opinion, he has the potential to become one of the two or three best players in the world in the years to come. If one day he comes to us and says that he wants to leave the club, then we'll discuss it."
