yep, about the only picture I've seen that constantly gets used "appears" to show fabregas gritting his teeth and maybe standing up to fagans face. HOwever when you really look at the picture you realise fagan is standing behind fabregas in the picture and fabregas isn't remotely looking at him. The gritted teeth look I'm sure is being used to show he was being agressive when in reality take a million pictures and one will catch him inbetween cheering the fans looking weird and thats all it is basically.
Other than that single picture i've not seen anything at all, the fact that the FA haven't dropped it is a disgrace already. Considering Brown in his interview where he claimed this in the first place lied about several things that clearly weren't true and attacked wenger for swaying the ref, accused the ref of caving to Wenger which normally gets a fine in and of itself when you question the refs.
Not to mention the whole time scale of this farce. Hull had to have their info on the situation in by a certain date, Horton was in the uk, doing smeg all all week up to the deadline, he left the country briefly AFTER the deadline, then the FA apparently without asking said they would give him an extension due to being out of the country. Despite the fact that obviously he could still have gotten them said "evidence" and that he was in the country when the deadline passed. Its a complete joke that the FA seem happy to continue with rather than tell Brown where to stick his nonsense.
