I don't know the lad and that video there a few pages back don't look great at all. That being said he's played for his country, is only just 24 and has quadrupled his value in the last year. Calvert Lewin was only about 23 or 24 himself when he kicked on and started looking like a proper PL standard player, in fairness the club might be looking at this lad and seeing a similar potential rise.
At a few million and already an international it's almost assured that we wouldn't lose money on him if we did move him on in future anyway, think a signing like him that's perhaps a gamble in terms of ability is a smart one, especially if the club is after perhaps a more versatile forward player alongside him.
