Good overview of De Jong. He's not the deep lying conductor we're desperate for, but rather he's the more advanced midfielder who progresses the ball through dribbling and contributing to the attack. He's the perfect kind of player for a midfield which already has its ball winner and controller. He complements that pivot/three man midfield perfectly. But if you're looking for a controller he's not the answer.
Frenkie de Jong is not an attacking player at all. Barca is trying to make him one, which is why he's dogshit at the moment. He does not like to attack the box whatsoever. He likes to receive the ball from the defense and transition it to the attackers (attacking midfielders).
Even more wrong is the "high risk high reward" remark. He's not high rist at all (unless you consider the dribbling high rist). He's not the guy that makes the final through ball or shoots on goal, he's purely transitional.
He's a defender much more than an attacker, which is why he played as a central defender for Ajax quite a lot. I'm sure his numbers at Barca at the moment point the otherway, but that's because they want him to be an attacker and he's trying (and failing) to be one. Frenkie de Jong is a defensive midfielder in a (not sure this is the correct term) double pivot. With a stronger tackler beside him and a creative force or number 8 (Ziyech or Donny at Ajax) in front of him.
Ah this dude actually says this as well later on. Still, he's not as much an attacker as he says. At all.
edit: wait maybe the twitter person isn't a dude.
Only logical conclusion; United sign him as a replacement for McTominay to play next to Fred. Would be the perfect fit for him positionally.
