If you are afraid to fail you will never succeed.
You look at wide players like Mitoma, Martinelli, Saka, Kvara, Dembele (when he’s not injured) and just have to wonder how we would function with someone who might not score as much but influence the game for a good chunk of the 90. It seems unfair to criticise him when the other attacking option are all bad for one reason or another but we already know what he is and isn’t at this point, and he’s not getting better.
I don’t think you can afford his type of player at the very highest level unless the player is Mbappe, and even PSG has struggled in big games when they don’t surround him with enough work rate.
