Eoin Larkin has questioned the attitude of the Galway players, claiming they are "not willing to put their bodies on the line for each other".
The eight-time All-Ireland winner says the Tribesmen's lack of team ethic is one of the main reasons for their failure to consistently challenge for the Liam MacCarthy Cup.
Speaking to RTÉ 2fm's Game On, Larkin said: "As a group they're not really together. They come out with all the right things in the media, that they are together now more than ever, but when it really comes down to it they're not really willing to put their bodies on the line for each other.
"I tipped Galway to win the league but they are really flattering to deceive for the last couple of years. They promise so much and deliver so little."
"It’s all about the individual, not the collective. To be a consistent, top-performing team you have to be willing to put everybody else before yourself.
"There were problems in the Galway club scene over the last 10 or 15 years, bad belts being pulled and things like that. They weren’t really getting on.
"I don’t think that has really gone out of Galway hurling. They don’t seem to be pulling together and playing the way they can as a team.
"There is no doubting they have fantastic individuals but that doesn’t win you All-Irelands. I know they have won one All-Ireland but really, with the panel of players they have, they should have been more successful."
Galway opened their Division One campaign with a big win over Westmeath but disappointed against Limerick seven days later as they fell to an eight-point defeat.
They face defending All-Ireland champions Tipperary on Sunday in round three of the Allianz Hurling League and Larkin says the game in Salthill is an "acid test" for the hosts.
"I tipped Galway to win the league but they are really flattering to deceive for the last couple of years. They promise so much and deliver so little.
"This should be the acid test for them this weekend. It'll show where they’re going for the year.
"Tipperary haven’t been playing that badly, they’ve just been on the wrong side of the result. That can happen at this time of year, especially when you haven’t a lot of work done.
"I wouldn’t be too worried about Tipp. They’re performing very well and it’s only a matter of time before they get two points on the board.
"There’s no bigger test than playing Tipperary and Galway have home advantage. If Galway are going to do anything this year they’ll have to be beating Tipp at home."
