Gerrard was only "world class" if you were England. You think France would swap him for Zidane? Italy for Pirlo? Spain for Iniesta or Xavi? These were the world class midfielders around Gerrard's time.
And they really wouldn't as they couldn't piss all over a bang average Portugal side, why? Because none of them wanted to or could defend. Most of the creativity in that side came from Beckham set pieces which is probably the only thing this side is lacking
