Kieran Donaghy believes Mayo could pose the biggest threat to Dublin in their quest for an unprecedented five-in-a-row of All-Irelands.
The recently-retired Kerry full forward was impressed with the Westerners' big win over Tyrone in Omagh yesterday and feels James Horan is building a squad capable of knocking the Dubs off their perch.
"Mayo look to be in a good place," Donaghy wrote in his Irish Daily Star column.
"Think of what it would be like if they came up against Dublin in the All-Ireland semi-final or final this summer. The goodwill towards them would be huge. It would be like Offaly in 1982.
"Mayo have been knocking on the door for so long many would love to see them get to the Promised Land. There's a long, long way to go, but there are signs of a signal of intent from Mayo with the way they've started the league.
"Mayo look well drilled already. They played a very positive brand of football yesterday."
