GAA director general Pauric Duffy has defended the current provincial championships and qualifiers, but says he would welcome any ideas on a change to the existing structures.

Calls for changes in the way the summer campaign is played out have gathered fresh momentum in the aftermath of many one-sided football games in 2013.

Speaking to RTÉ Sport at the All-Ireland series launch, Duffy did reference such encounters, but also singled out some notable achievements this summer.

"Teams have suffered some heavy defeats. In the Connacht Football Championship, Mayo are dominant at the moment. Yet, it’s not that long ago that other counties were winning titles. It’s a cyclical thing.

"I am worried about the situation in Munster football where two counties are continually to the fore.

"However, Ulster this year saw Monaghan emerge which shows that there is still a high level of unpredictability. London getting the Connacht final was unique.

"As for the hurling, we’ve had great championships in Leinster and Munster and the victories of Dublin and Limerick have really opened things up," he added.

"Overall, I would have to say that the provincial championships have a place in the calendar. Alongside the qualifiers I think they give a good balance to the summer and satisfy the needs of our supporters.

"If someone can come up with a better system that meets the needs of all the counties then we will certainly have a look at it. However, it won’t be easy to find an alternative that will be acceptable to everyone."
