Lack of warm up, pre existing injury that wasn't obvious or just bad luck?
It does seem to be a curse for us - I can understand Welbeck , at his age, getting a hammy but Lamptey and now Sarmiento are both young lads and you would imagine not prone to this kind of injury.
No, it appears not!The lad is a little fragile!
Has he ever completed a full 90 minute game of football in England?
