Robinson said in an interview that he doesn't know what he can say, which obviously means there is something he isn't saying; something more than we currently know. What that may be, well that's where speculation comes into it. It's hard for me to believe that Lego can play like he does, as often as he does, with an injury. He does everyone 100% - even the way he charged over against Rochdale to stick up for Hall! I could be wrong, I don't know, but I'd definitely be a bit surprised if it turns out to be true.
As a side note, I find it hard to believe that anyone who wants to be taken seriously could quote The Sun - The fecking Sun! - as a source of any kind. Taken to hacking fax machines, have they?!
