Mate, you are certainly not the only one feeling the nerves. It is written all over the face of Richarlison when he is on the pitch, given after this long goal drought. About the coaches, you are right. Ancelotti is betting on more than stats or results. He is not using Richarlison as a short-term solution. This is also about relationships. Ancelotti made Richarlison a "phenomenon" at Everton since he treated him more like a son than a player. He is now attempting to replicate that play with Brazil. Is it logical on the outside? Not really. Yet, considering all the injuries and mental health struggles Richarlison has been through (therapy literally “saved his life”), it becomes clear why a manager with a bit of empathy and patience would keep him. Had this been 2014, the guy would have been Fred-style thrown under the bus, scapegoated and forgotten. Football is changing, whether it is good or bad. Keep the skepticism, but see what happens when Ancelotti is able to bring the guy back with his quiet leadership. He is betting on the man, not the moment.
Well, one of the things I like most about Ancelotti is that he is a great person and his players see him as a father, and achieving that empathy seems to me to be the most valuable thing I think that is the reason why they love him so much, and I think what he is doing with Richarlisson is good, Everyone deserves a second chance, Sometimes life's adversities keep us away from things of success The important thing is to get going Brazil has already recovered and is in the World Cup What remains is a lot of work.
Improving the attack of the Brazilian national team will be a very difficult task, so I hope the coach decides to do some experiments in the next games, because since Brazil is already qualified, then he can afford to lose. I don't know who he will call for the next games, but the options
seem limited to me, maybe he will call many players from the Brazilian league. There is still a long time until Brazil's next game, if I'm not mistaken it will be in September against Chile, which is the worst team in this group.

I find it hard to believe that Chile finished in last place, I don't see them improving their position, they no longer have a chance of qualifying
