Partey missed two thirds of the season, Jesus has missed significant chunks. But yeah, we have been lucky- Gabriel, Saliba, White, Rice, Odegaard and Saka have barely missed a game between them.
After a few years of this, you have to think it is probably not entirely due to luck.
Jesus and Zinny have both missed a few games, Tommy as well but yes, on the whole we've been okay on that front.
