I think that Gavi understands his role better with Frenkie (or Nico infact). He takes more responsibility to be the "conductor" when he was with those two. With Pedri that role is firmly reserved for Pedri, and Gavi falls into a supportive role he hasn't quite defined - yet.
That's not to say that long term the best partnership will be Gavi-Pedri, just that right now Frenkie is the glue through experience, understanding his role and being in impressive form.
Yeah for next game I'd probably like to see Gavi and Frenkie together, with Pedri possibly taking one winger role. Very unlikely of course, almost as unlikely as Puig starting which is what I would really like to see, but still.
Pedri was very immobile last game, but is usually very mobile and thus also often out of place I think. I think it is sometimes very tough to play beside him (of course it is the same with Gavi and even more with Puig - they are very mobile too).
This is a thread about Gavi. I liked some attempts from him yesterday very much - the entire team struggled, but he was the one who managed to do something sometimes. He is very weak a lot of the time though, not really managing to take the step to play with adults yet I think. He needs some time.
