There is a lot of targeting on Barton, i wouldnt say todays tackle on Alonso was the worst tackle ever,
possibly not even of the game, Alan Smith made a lunging tackle earlier in the game but thankfully he missed the players legs, a two footed dive. That had potential to be much worse and nothing was really said.
If Barton had made a lunge and missed like Smith did, there would have been much more chat about how it could have potentially been the worst tackle in history.
Im not defending Barton because I think he was stupid to go in on Alonso and get sent off...
Im more stating that there is a lot of targeting and bandwagon jumping given his history, he will never be allowed to forget that and as long as there is that much attention given to him I cant see him being a good player.
