The personnel maybe in place in the squad.
For example, I like what I have seen with Harwood-Bellis and Garcia who seem close to stepping up. Foden is imo already ready to step up, and I don't understand why Pep is not using him more. He has got goals in him, and assists. Rodri may or may not be able to replace Fernandinho in midfield. He is not quick and nimble like Fern, but he is powerful and technically very good. Jesus could replace Aguero. Sterling may also be able to play inside more often.
