He's in his first season and has played 21 matches for Vitoria. That's it. And 2 matches for the U20 national team.
He's 21 which is not even very young for a Wing Back.
And he's a wing back, which is literally the least impactful position in football and usually the cheapest. I think we're overspending a bit but I hope our scouts did their due diligence on this one.
