He is a player that hardly get injured on the field and that's what helped his career because while some players consistently get months injuries he is always free from that, when Lionel Messi was in Barcelona injuries wasn't his problem and even until he has moved to so many teams and his age still no worries for injuries, I most say that his body is gifted strong for soccer, although is very early to no whether Yamal will be troubled to grow because of injuries as he hasn't been having series of it yet and I believe he wouldn't face what Neymar go through on that as we saw on his career.
If Yamal suffers injuries and doesn't return to his former form, it's true that he could be negatively affected, like Neymar. His career is currently on track to become one of the best players in the world. I think the biggest obstacle to that would be a serious injury like Musiala. I hope that doesn't happen, and the young player can demonstrate the same performance next year. I believe he can be very successful with Barcelona for many years to come.
I wish there shouldn't come a time when it will be the reason why he will be unable to play as always but as I insinuated he may not have such fate in his career because if that will be the case the indication could have been coming very often seasons ago but on the contrary all this few times are not something to really say that he might suffer on injury mostly on the career, so actually I just believe that his career will be a non injury setback and besides his labor in Barcelona shouldn't be too overwhelming for him since there are a lot of players like him.
