Borussia Dortmund assistant manager Jorg Heinrich has conceded that Jadon Sancho will leave the club within the next two seasons - and also backed him to become of the best players in the world.
England ace Sancho, 19, is believed to be Manchester United's top target for next summer as Ole Gunnar Solskjaer tries to turn his ailing side back into contenders.
Sancho is also admired by Liverpool boss Jurgen Klopp, who described the £100million-rated winger as “an exceptional talent".
Dortmund's Bundesliga rivals Bayern Munich are another team keeping tabs on his situation, though the Premier League is expected to be his next destination after quiting Manchester City for Germany two years ago.
The talented winger has become a permanent fixture in Gareth Southgate's England squad and Heinrich believes it's only a matter of time before he seals a big-money move.
"Jadon can become one of the best players in Europe, or even the world," Heinrich told Omnisport .
"It won't be easy to keep him at Dortmund. We hope he plays one or two seasons longer but we all know very, very big clubs with a lot of money want to have him in their team.
"He should know Dortmund is an excellent place for young players to play consistently and to develop on a very, very high level."
Sancho has again impressed this season for Dortmund, scoring three goals and providing six assists in the Bundesliga.
However the German giants have underwhelmed so far and sit eighth in the league, though they are only four points behind surprise leaders Borussia Monchengladbach.
"Our aims before the season were very, very high," Heinrich added. "We announced we wanted to win the league this year.
"The season so far hasn't gone that well, but we are not that far away from the top, so we are hoping we can fulfil our aims and take the top of the league."
