I understand him, but he is just missing a point. They are letting Ortega go, that is already done, Ortega has been told to find a team already. They planned on having Trafford and Ederson at goal, changing based on the game, Trafford is younger, Ederson is older, and they hoped to have Trafford be great as much as he can with time. Like at least make it so that they can do better job, so that would be important thing for the future, growing their own talent for a while.
Donnaruma is a weird situation, that was something nobody expected, city couldn't have known that would happen, so they were caught off-guard like all of us and now they are realizing there is a chance they can get him, and that is definitely a huge plus.
Donnarutmma surprised everyone, including the teams that wanted to take him, including Manchester City. Surely, many teams are also interested, and it's no coincidence that the player decided to leave now. According to him, he did it to put the club in difficulty.
