I did not say Garnacho possess the same talent as Ronaldo nor do I think that and I also do not sit here and try to forecast where Garnacho will be in 10 years time. Anything can happen to a player, I remember Deli Ali was once the young king of England, now he cannot get into any side he plays for, only 26.
Regarding Garnacho & Ronaldo, I said that people wrote off Ronaldo at a very young age. He made mistakes and was not fluent, he frustrated a lot of the fan base. He was basically young and people did not want to see how he grew. No one expected what came after but his talent was there and obvious.
I'm simply reminding you, it's naive to write off a player, who is 19 years old, has about 15 years left in the game, played 2 professional seasons and has probably been the most consistent player we have had in the worst season Man United have had in a very very long time.
