Pat Spillane believes Derry will not win this year's All-Ireland despite being crowned Ulster champions for the first time in 24 years over the weekend.
The Oak Leaf County defeated Donegal by 1-16 to 1-14 at Clones on Sunday to lift the Anglo-Celt Cup after previous victories over defending All-Ireland champions Tyrone and Monaghan.
But Spillane can't see Rory Gallagher's men lifting the Sam Maguire later this summer and claims Donegal are "very,very much in decline".
He told RTE's GAA Podcast: "Can we take away anything from the provincial finals? Obviously, you can't take anything away from the Munster final and Leinster finals.
"While we're reading a lot into the Ulster final, to be honest I didn't rate Donegal. I think this is a Donegal team that are very much in decline. Very, very much in decline.
"I saw Marc Ó Sé today, saying he had it (1.) Dublin (2.) Derry (3.) Kerry. Now, I wouldn't agree with Marc.
"Are Derry going to win the All-Ireland? No, they're not. Very simply, I'll tell you why they won't. They just don't have a forward line of the quality that's required to win an All-Ireland.
"They won't win an All-Ireland. They haven't that top quality forward to deliver an All-Ireland. (Shane) McGuigan is a good forward. But if you go back to Donegal (in 2012) when Jimmy (McGuinness) and Rory won with them - he had Murphy, he had McFadden, he had shooters. Derry don't have those top quality forwards to win. That's my belief."
