Laois's win over Dublin strengthens the argument that the Leinster championship should contain six rather than five teams, according to RTÉ hurling analyst Cyril Farrell. 

The 2019 Joe McDonagh Cup champions produced one of the biggest shocks of modern times, beating Dublin by two points in Portlaoise. 

They were already bound for the Leinster hurling championship in 2020 where they face a stiff challenge to retain their top tier status. 

The Leinster and Munster championships each house five teams but it is only in the eastern province that teams are at risk of automatic relegation. 

A Munster county would only drop into second tier should Kerry win the Joe McDonagh Cup and even then, they would still have the lifeline of a playoff. 

Given that the provinces are already treated differently, Farrell argues that six teams wouldn't upset the Leinster championship and would aid the development of those teams now hovering between the two tiers. 

"Maybe there isn't as big a gap as people think (between the tiers)," Farrell said on The Sunday Game. 

"When Galway only beat Carlow by six points, everyone was saying they should have beaten them by a lot more. But they weren't able to beat them by a lot more.

"The gap is closing. There should be the six teams in Leinster, so it'll give teams a chance (to develop). 

"It's up there with Antrim beating Offaly and Kerry beating Waterford years ago. On a wider issue, it shows that there should be six counties - whether it is Laois, Carlow or Westmeath - in Leinster.

"It doesn't take away any Sundays and it leaves you with an even number of teams."
