Eh it's an exaggeration obviously about the championship. Most of their premier league players, bar Coleman, are squad players for lower table teams. It's subjective but there are many higher profile and more expensive championship players than the likes of Meyler, O'Shea, etc.
What's not subjective is that Serbia, Austria and Wales all have much higher profile players, that play in better teams and cost much more.
Still, big fan of this Ireland team. Hope they qualify again.
