On Sunday afternoon at the Emirates, we were supposed to discover about Arsenal's new approach under their new Spanish manager Unai Emery.
Instead, we learned about Manchester City's new approach under their "old" Spanish manager, Pep Guardiola.
Arsenal have a fresh manager, but City have fresher ideas, and this match could prove more significant in signalling the away side's intentions for this season.
A new manager's first starting XI is considered the template the manager's future tactical approach. But for Emery, a reactive, pragmatic tactician, his first team selection was designed to cope with the specific threat of Guardiola's side.
