That's why in football, a coach should not depend on only one person. A coach type like Pep must make an effort to "create" another person with the same level and skill as Rodri. He was too late to implement it and didn't do anything on Windows summer transfer ago. He feels the current squad that he has is enough strong to compete on the next session, Where in fact he forgets if a player has a vulnerable and unstable period.
We can't expect too much from a coach. This is an accident that no one could have predicted during the season. Pep cannot prepare a great player in advance and wait until Rodri gets injured and replaces him. This can be considered a disaster for Man City when many key players are injured at the same time. Even with the likes of Mateo Kovacic and Matheus Nunes, they still cannot fully take on Rodri's role.
When I ask AI, A type of player who has the same skill as Rodri are; Martin Zubimendi, Oshua Kimmich, Ederson, Morten Hjulmand, Frenkie De Jong, and Samuele Ricci.
Among these players, I see Real Sociedad's Martin Zubimendi as the most promising candidate to replace Rodri. He has a similar playing style to his senior in the Spanish national team. convincing Zubimendi to leave Real Sociedad mid-season could be a big challenge, but it is entirely possible with the attraction of the Etihad Stadium team. But who will guarantee Martin Zubimendi will have a starting spot when Rodri returns?
if my choice, This type is suitable for Kante also, but because of its age, Pep may not consider him as don't have speed and power like Rodri have.
Kante may not be his peak self, but at 33 he still possesses outstanding quality. He is in Saudi Arabia now, I don't think he would be ready to come back to the Premier League to be Rodri's backup.
