Borussia Dortmund are tracking Chelsea striker Callum Hudson-Odoi.

Chelsea face a battle to keep hold of the teenager.

Hudson-Odoi now has BVB, Monaco and RB Leipzig keen to sign him when his contract runs out in 2020.

The youngster was part of the England Under-17 World Cup winning team last year and also started the Community Shield.

However, he has since only got on for 30 minutes, on Thursday, against Bate Borisov in the Europa League.
