The first sentence of the second paragraph is a bit clunky. Had to read it more than once. Maybe that's more of a criticism of me though. But I don't think you need the clause about who they played for.
The other thing I noticed was that the comparison between the media treatment of Lampard and Gerrard could have been made much stronger with some quotes from a variety of sources backing up the claims, otherwise it comes across as a bit of a paranoid conspiracy theory. And if you're gonna be a sports journalist (at least a decent one) it'd be a good idea to hide the fact that he's a City fan, because it was pretty obvious from the opinion piece. You've got to at least have the facade of being impartial, even if it is going on a fan website.

And even he confessed that that was more down to him being a lazy bastard than anything else.
