The loan move from Monaco is good but if Barcelona sells him directly to Monaco it will be good because it will be difficult for Ansu Fati to get back to his best form, Barcelona put a lot of pressure on him from the beginning and that is what they are doing with Yamal and if they did not stop they will spoil Yamal career, I’m not a Barcelona fan but Ansu Fati should leave Barcelona permanently and start a football new career.
With Ansu Fati, Barcelona haven't given up on him completely. They're trying to see if he can get back to his pre-injury form. Fati was really good before his injuries started. The club is waiting to see if he can get back to that form because he is still young and has time to recover. If he gains a little form, even though they might not keep I'm, they can sell him for a reasonable fee and make some money off him.
On the topic of pressure, there is simply no way you'll play for Barcelona and not have a lot of pressure. It's like playing for Madrid and expecting not to have pressure. The fact that you are a teenager doesn't change that. There was pressure on all the young players of Barcelona who made it through the ranks, so it's nothing new.
Barcelona didn't spoil Fati's career; injuries did.
It's funny how it's not even Barcelona that is hyping Yamal, but the whole football world. People are watching and seeing what the kid can do, its only normal for them to be amazed.
