Do you think Garnacho knows who it is? Who this Faz fella is?
He is signing autographs before a game, instead of encouragement you hear people saying improve your first touch, make sure you pass. Its not like its a 12 year old kid saying this, he is a grown man.
Garnacho is 20 who is in his 2nd year of football, younger people seek greater validation, which is why it impacts him. Ofcourse he will learn from this, but you cannot say to a 20 year old, you should be used to this.
Do people understand footballers are not robots and are actual humans? Different people get affected differently.
Would you rather the players ignore fans and not give them the time and day? Treat ever fan as a youtuber as they cant tell who is who.
