Brian Talty believes Galway will have to approach this weekend's game with Dublin in Croke Park with a "different mental attitude".

Former Galway star Talty - who worked with the Dublin side as a selector under Paul Caffrey - is expecting a much-improved performance from the Tribesmen after last weekend's dismal reverse against Monaghan.

And Talty insists they will need to bring a different approach to the game.

"A lot of people were optimistic about Galway until last weekend," Talty told the Irish Independent.

"Now sometimes it happens where you have one bad performance you go from being a huge challenger to being nothing.

"If they played again like they did against Monaghan they have no chance.

"I expect a different approach because now you are challenging the best team in the country and the best team that has been around for a long time.

"There will be a different mental attitude, I'm sure."
