Injuries are indeed an obstacle to a football player's career, but there are also players who, even though they are injured, can still give their best performance. It's just that this case is very rare and the most frequent is a decline in performance suffered by the player. Ansu Fati has indeed become one of these victims and it is inevitable that now he has to bury his hopes of returning to Barcelona's main squad.
We know that with Barcelona's current situation, of course they also don't want to extend Ansu Fati's contract and instead it would be better for them to sell him and generate some fresh funds to bring in the players they are targeting. We know that Nico Williams is the ideal player for Barcelona and he is the right choice to fill the left winger position. It's just that Barcelona has to dig deep into their pockets to redeem their clause from Bilbao. The duet of Lamine Yamal and Nico Williams will make Barcelona often cook their opponents.
Yes, injuries are one of the things that are very feared in football, especially by players. Because the injuries they experience will cause their performance to decline, as it is said, only a few players can be stable in their performance even though they have just returned from their injuries.
Even well-known players are not immune from this, for example Neymar. Neymar is one of those players who is very susceptible to injury, I don't remember how often he experiences this, and as far as I know, almost every season he always experiences it and repeatedly has to rest.
And even in his current team, the injury he suffered ultimately became something that caused problems between him and management. Yes, even though this is not his fault, it is the impact that injury can have.
