You made great points about Donnarumma and Manchester City. You are right that Donnarumma is top goalkeeper and his youth and ability to adapt quickly would make him perfect fit for coach Pep Guardiola. When it comes to Manchester City it is frustrating to see them struggle despite having great team and world class coach. Problem likely is not just about their skills. I think their can be low team chemistry or issues with their tactics. Pep will have to figure out what is wrong to get them back on track.
Well, I will commend Pep and city for signing a new goal keeper but Manchester city problem is not the goalkeeper but the defence. It seems Guardiola is already out of ideas managing this team after all he's done for them in the recent years. I don't understand why he let go of Akanji when their defense is in shambles and then assumed a new goal keeper would solve that problem. Ederson was never a bad goalie but the weakness in the defense made him look like average goalkeeper and the same thing will happen with Donuramma if nothing is done about the poor performance in the defence.
