I don't know for how long Pep plans to stay at City, but if he stays there is no better player for him. If Pep could bake himself the perfect midfielder it would be Wirtz. And I would hate it...
Not that sure I would like that, Pep tends to be a bit over the top trying to manage players like Wirtz unless is a Messi and even with Messi he got mad lots of times, but is Messi, Pep does not eat glass for lunch either.
Pep tends to have shorcircuits from time to time with Kevin (the one closer to Wirtz, Messi in his squad) and also Foden (who has been "trained " by him since a very early age) goes up and down in his level because he knows that the bench it's always there waiting if not following orders or not delivering with a new role or position.
I would preffer Wirtz in a team with a bit more freedom. I'm not saying it won't work, in fact Xabi has lots of Pep things regarding keeping first team time, changing roles, etc, but I feel Xabi is more vertical and gives more license to his players to risk more the ball than Pep.
Wirtz in Real, Barca, sounds better, I want the lad to free roam and be himself and become an alltimer with all the fame he deserves.
From Bayer, Palacios suits City and Pep like a glove, he'll do as he is asked and it's not as bad for us as football fans if he has him in a leash instead of having such a promising and special player like Wirtz in such scenario.
