I cannot believe people's expectations around here. I don't think it's unfair to say that 99% of the people commenting in this thread have never seen Diallo play live and your opinions and expectations are based on highlights videos. We are talking about a 18 year old boy who has NEVER played 90 minutes of senior football in his life. In total, he has played 59 minutes of senior football and has been in the squad for Atalanta men's team for 20 games.
I see people saying he will hit the ground running and become a starter in January. Then other are saying he will take a while to start playing but then will be this amazing player who will transform our season. I just cannot understand on what are all of you basing these outlandish statements?
He may well be a fantastic talent and might not even need a long time to adapt to the Premier League, life in England and his new team but expecting him to be a game changer? I'm lost...You do realize that senior football is nothing like academy football? He will face men who are used to playing against Salah, Bernardo Silva, Rashford, Pulisic and Son.
I'm writing this for your own sake. Be reasonable and realistic. I'm super excited about Diallo but I honestly expect him to spend a few months in the U23s and have very wobbly games for the first team when given the chance (if at all this season). Same for Pellistri.
Do not make Diallo a failure of your unrealistic and unreasonable expectations.
