Pat Spillane reckons Galway aren't attack-minded enough to beat any of the top four teams in Croke Park.
The Tribesmen will face Kerry in their first game in the new Super 8 series after regaining the Connacht SFC title seven days ago, but Spillane believes their emphasis on defending will only take them so far.
"I don't believe Galway would beat any of the top four sides - including Mayo - in a knockout game in Croke Park," he wrote in his Sunday World column.
"They are a work in progress. They have youth and a decent subs bench, which is a great starting point. All they need now is to believe in themselves, focus less on the opposition and concentrate on their own strengths."
The Kerry great also questioned the need for manager Kevin Walsh to hit back at his critics after the Connacht SFC final win over Roscommon.
"Kevin Walsh was quick to fire a few barbs at his critics afterwards," he continued.
"He wondered whether we knew what we were talking about when we mention words like transition. I thought it was an odd reaction because the golden rule in sport is that the winning manager does not need to defend his tactics.
"I've never heard Brian Cody, Mick O'Dwyer or Jim Gavin having a pop at their critics after their team wins. On the other hand, Mickey Harte and Jose Mourinho have made it into an art form."
