Borussia Dortmund's ambition to poach the best English youngsters could see them land Everton's attacking midfielder Anthony Gordon.
The England Under 18 international is regarded as one of the finest talent to have emerged from Everton's Academy since Ross Barkley and has already made a senior appearance, in a Europa League game with Apollon Limassol last December.
Gordon, who is not 18 until February, has made such progress that it has pricked the attention of Dortmund and Bayern Munich.
Arsenal have also shown an interest.
Dortmund moved just over a year ago to land Jadon Sancho from Manchester City.
The 18-year-old has since gone on to become one of the outstanding young talents in Europe with five goals in 19 appearances this season, and earned his first England cap just last month.
Everton's Ademola Lookman enjoyed a productive loan spell at Leipzig last season, and scored five times in just 11 games.
