Colm O'Rourke believes serious consideration should be given to breaking Dublin into three or four teams as the capital's domination of the Gaelic football shows know sign of easing up.

Dessie Farrell's men eased into another All-Ireland SFC final on Saturday night with a 15-point defeat of Cavan.

They will attempt to win their sixth Sam Maguire in a row in two weeks' time and on current form it's difficult to imagine Mayo or Tipperary, who meet in the other last-four clash on Sunday, halting the Sky Blues' relentless march.

Discussing the current footballing landscape after the match, RTÉ GAA analyst O'Rourke said: "It shows the gap that there is in class between Dublin and the rest. They're like the Grim Reaper, whenever anybody comes here they just put them away with ruthless efficiency.

"They could have won that game by 20-pus points. This is the future. This isn't going to stop this year or next year. We could be looking at Dublin going for ten-in-a-row, they have under-20 teams coming up. Their under-20 team is already in [this year's] All-Ireland final... this is a pattern.

"Dublin have created a monster. The GAA at central level need to decide what's going to be done about it. I'm not one of those that says they should be cutting Dublin's finances. That's not the answer because that finance is going into schools and creating a lot of new players and new clubs.

"The only answer for the future has to be that Dublin have three or four teams. Otherwise everybody else is wasting their time.

"Eventually somebody is going to have to sit down and have a serious discussion about what we're going to do with Dublin.

"Not only have they the numbers, the finances and everything else, they probably have the best players we have ever seen," he added.
