Name me one elite player that broke his ankle and tore his ligaments and came back elite! Never happened. Look just at Ox - and the dude didn't even break his ankle and still he does not look as if he belongs into top 4 PL-teams anymore. Also watch videos with MD's on youtube, there are all like "at least career alterning" which is chiffre for "he won't hold his level". And of course my whopping 14 years experience as a NFL fan where such drama happens more often and guess what: broken ankle and tore ligament = retirement (and yes, Alex Smith came back with something similiar, but just to prove a point and then retired). Harvey might come back and be able to play in the Championship or even for low PL teams, but never for elite teams.
It's not that I do not wish Harvey the best and maybe the super slim chance comes true that he broke it but not tore some ligament or whatever but I am not that sissy to deny the facts and roll into false hope.
Does Frank Lampard count? [yes, the 'o' is meant to be there]
OK, he only went on to win three PL titles, a Champions League and several FA Cups (four, I think) after breaking his leg aged 18, but he might be in with a shout, whatever we think of C****a.
Thinking about it, there was some Argentine bloke. Diego something or other. Had his leg - ankle, to be precise - broken in 1983 by what was reckoned to be one of the worst tackles in the history of football. Didn't achieve much after that.
Well, apart from the two Serie A titles and a UEFA cup. Oh, and carrying his team to the 1986 World Cup title virtually single handed (literally, in one match...).
But no, no player who broke his leg/ankle ever managed to play at the highest level aga... wait a moment....
