There are far too many tales of young players who started early and whose careers were blighted by injuries because they were playing intense football while they were still growing.
For us: Fowler, Owen, Gerrard, Rob Jones are obvious ones. Gerrard grew out of it to a degree but was a proper sick note when he was still growing and going hell for leather all game.
Giggs was another - although he had a long career, he had to change his game because of his tendency to pick up hammy injuries. Like John Barnes, he moved from explosive winger to playing in the centre where there was less running.
Then you get the likes of Sterling who just fall off a cliff, probably burnt out. Ben Chilwell the same.
It's not good for boys to be kicked off the park, week in, week out, by grown men.
I think we're handling Rio just fine. He's too good to leave out, he's too young to throw to the wolves. Thankfully he's also not the kind of cocky little showboater who demands to be booted up the arse 3 or 4 times a game.
