Borussia Dortmund are reportedly set to join Arsenal in the race for Celtic starlet Karamoko Dembele's signature.
The forward, just 16 years old, made his first-team debut last season in a 2-1 win against Hearts.
Dembele was recently handed a new contract that runs until the summer of 2021, but his ability has caught the eye of the likes of Arsenal and Dortmund, according to Bild.
There have even been links to Juventus and Paris Saint-Germain for the teenager, who has yet to make a first-team appearance this season.
A right-winger by trade who likes to cut inside onto his left foot, there have been unavoidable comparisons with Lionel Messi.
As such, there is also a growing clamour over his international future, as Dembele is eligible to represent England, Scotland and Ivory Coast.
