Pedri, Ilkay Gundogan, Gavi, Frenkie de Jong, Fermin Lopez and Oriol Romeu. On the face of it, that is a midfield most teams would sell their souls to have. The technical excellence, the pure quality, the experience, the youth, the elite potential; that roster has one of the best combinations of players on the planet. And they all play for Barcelona.

But if you look beyond the names; if you look beyond their individual attributes, they are still incomplete. Elite, sure, but also incomplete. At the moment, it's challenging for Xavi to field a complementary midfield while using his best players because his best players don't necessarily form his most complementary collective.

So how does he go about solving that issue?
