Nani is an awesome player, one of my favs and I always argue with the old man who is better him or Bale but I have to say I'd be surprised if I ever saw Bale one day do what Nani did there. Shockingly bad. What Nani did there is Sergio Busquets level of play acting and I hate the play acting more than the diving itself. The rolling about making out you've been shot did come from the Spain/Portugal region of football and I remember watching us in the CL in the 90's when we were the only team in it from England, seeing those players doing it against us and thinking what the hellbare they doing. Nowadays you expect to see Barca or Porto etc to do it every game.
Even if England has a starfish or even Rooney going going down on occasion or other British/Irish players like Bale you know that the worst cases of divers or rollers to make their infamous marks have been foreign. Drogba, Torres, Nani and now Suarez.
Although with Nani I dont think hes trying to con the ref, he does just have those over the top reactions at times. The weird bahaviour at Anfield when Carragher should have been sent off and cut his leg was like what he did in that headbut clip, despite the bad tackle on him, was just strange and dramatic, un-premier league like IMO.
