5 teenagers who could turn out to be more expensive than Anthony Martial

#4 Alexander Isak – Borussia Dortmund

'The next Zlatan Ibrahimovic’ already has a lot going for him

17-year-old ‘next Zlatan Ibrahimovic’ Alexander Isak is en route to break Martial’s record because of two reasons: he’s a striker and he’s European.

Isak has shown a lot of promise and has no release clause as such with Borussia Dortmund, but should he transfer by the 2018 summer transfer window, he could very well break the record set by Frenchman, Martial.

Even though he’s only 17, Isak has represented and scored for the senior Swedish national side – something that could very well open new doors for the youngster. And having Ibrahimovic’s recommendation is something that’ll help his market value rise, too.
