We have to play Petrov. We simply haven't got the players to replace him with. Ireland cannot play the deep lying role. That means one of Sidwell, Osbourne, Salifou or Hogg playing. We cannot sacrifice the strength of having two primarily defensive players in the team as we are setting out to attack all out with three wingers.That is why the only change I'd make would be Cuellar in for Dunne... That said I would also consider a more defensive line up where we sacrifice one of Albrighton or Downing for Ireland.
