Are people seriously saying that Xavi and Iniesta couldn't perform in EPL...?

I'm an EPL lad but I want to know which peanut said Xavi or Iniesta wouldn't be able to perform in the EPL? It is a stupid thing to say but the way you start a new topic about it, it's like the whole EPL thinks Xavi and Iniesta wouldn't be able to hack it in the EPL. Still, Fabregas OWNS!
