I answered your question, it was a dumb hypothetical. Pep works with what he has and has prioritised a striker because we're crying out for one.
The holding role is absolutely pivotal to the football his sides play. He's had Xavi/Busquets in there at Barca, and Alonso/Lahm in there at Bayern. At City he's had Fernandinho, and Rodri doing the bare minimum against the league's dross.
He's an enormous weak link and I'll be absolutely astounded if we don't sign a 6 next summer, possibly even in January.
