It's not just his hammies, though.
Ankle, calf, knee, thigh, hammies...just needs to break a foot and he's done the whole leg. And all were serious injuries.
I used to work with some of the MotoGP guys and also some former basketball players back in the day (not bragging) and every single one of them told me that you never ever recover 100% from ankle and knee injuries. You always leave some in the operating theatre.
When I played, I did both ankles, the right one pretty bad...played a pass, saw a big fucker coming right at me with a late nasty tackle, jumped over it but then landed badly and ended up having my peg face the wrong way. Puked my guts out then passed out on the pitch, such was the pain. I was out for months and was genuinely concerned I'd never be able to walk properly again, let alone run & play football. Luckily it healed...but...pre-injury I was a pretty fast fucker, I could put in sweet crosses and would bang in a fair few free kicks, also had a decent leap...I tell you what, when I returned, despite having really looked after myself, done proper rehab & reinforcements and all, I was never the same. It wasn't just psychological either, you just feel your body ain't the same and it's an atrocious feeling. In my case, it's not one yard of pace I'd lost, it was friggin 5. If I had a proper career, it'd have ruined it in no time, for sure. Obviously I wasn't an elite pro with access to the very best facilities & docs, didn't have big wads to spend on specialists outside the club's etc etc, but still.
I feel for the Netos and Sessegnons of this world, and yeah there's always the chance you could suddenly become Iron Man, but far more often than not, you'll just end up injured again. Happened to so many players, like two of my all-time faves...the great Marco van Basten and the class Fernando Redondo.
