One thing that I think we're underrating, is how he's managed to adapt. My biggest concern when he arrived was whether he was another "too slow for LW and too weak for CM" type of player.
We've had players like Denis, Arda and Coutinho who are very much like Pedri in their physical limitations.
Denis came as a talent from City. Arda as a versatile player from a hard working Simeone side. Coutinho as a technically gifted player putting in great performances in both NT and Premier League.
Different backgrounds, but very much the same type of skillsets. There are probably more examples.
None of these managed to do what Pedri did, which is to adapt to a position that actually exists in this Barca side.
