Yea right. Behave.
If Guardiola sorts your frail defence out then you should walk the league. Jesus and Aguero with deBruyne, the 2 Silvas, Sterling and Sane..ahem, you're hardly lacking creativity and strike force although Guardiola seems to not fully trust Aguero.
Guardiola prefers more fluency but Aguero's still up there with the most lethal of finishers, a world class striker.
Compare that to Pogba, Martial, Mkhitiryan, Mata, Lukaku and Rashford I'd say your lot can hold your own even without considering the manager's tactics. If you do get Sanchez though and sort the defence then you will be pretty much unstoppable.
