His injury record is freely available online, and no, he missed a total of 7 games in his first 4 seasons. That’s literally half of his career here. In 18/19 he was still good until, you guessed it, OGS came in, and he had a groin injury during the first leg of the PSG match. Had some issues during 19/20 but were available most of the time, and by his own admission, played the first 4 months of 20/21 injured, until he was out of the team and got the knee injury. Been crocked ever since.
You can say that it doesn’t matter now, he’s still a crock, but ‘Martial has always been injury prone’ is just another myth to add to the already quite sizeable list of myths about him.
