I've not seen the player outside of Youtube's posted here, but even from those, I question what you're saying here.
He looks like his 'best' position is the same one Martial plays in: coming in from the left, as that's where he scores all his proper goals from in the vid.
From the right, he looks to cross or pass or simply blast it at the goal, whereas from the left, he's calm, composed and is slotting home. He never uses his left foot, which is a massive hindrance whilst coming in from the right side of the pitch.
From the right, he looks like a ball-playing winger; from the left, he looks like an accomplished wing-forward - he doesn't look like he has both sets of attributes irrespective of the wing he's on, so it's a pick your poison scenario: goals from the left, or assists from the right.
I've heard he's highly rated, but he looks underwhelming in what is supposedly his best highlights from a season in a weak league. If the links with us are true, it will be good to get a proper look at him during the Euros.
