I dont know if Pep has any time for this in the summer with the euros.
But I was hoping he could work with Jack on getting him use to do a "Bernie-like" midfield role next to Rodri, so he can play with Doku, Bobb or Savio, other electric wingers.
He keeps the ball well and physically is pretty strong. He just needs 360 vision, theoretically he should be better than Stones in this role next to Rodri. Perhaps it would open his passing range that we saw in Villa when he had this more central role to playmake.
I think Nunes should also be molded into a similar role, both also have good ball carrying ability.
I think a switch to a 532 or 541, either like Inter or Leverkusen would help this team defensively as well, Grealish and the like would do well in a formatiom like that I think.
