He is incredibly gifted physically. Certainly he is one of those fabled physical midfielders BBZ dreams about despite his appearance.
Actually Frenkie is a mix of s technique and physique, yes.
Technique: check
Off the ball movement: check
Pace: check
Stamina: check
Height and aerial duels: check
Some muscles: check
Defending: check
IQ: check
Now, imagine that we have two machines like Frenkie who are technical, fast, tall, strong, smart, good in defense.
No offense to other players, but look at how much more Frenkie can offer than guys who are only technical but poor in physical terms like Busi, Puig, Arthur etc.
Again, imagine one technical Barca Dna midfielder and 2 Frenkies.
That is way better than 3 light midfielders, isn't it?
But I know, there aren't many players like him.
But still... imagine two machines like him in midfield.
