Experienced Galway defender Fergal Moore fears that the Tribesmen could face a backlash from Waterford at Walsh Park on Sunday.
The two sides enjoyed contrasting fortunes in the opening round of the league with Galway destroying Dublin by 0-28 to 1-12, but there was disappointment for Waterford when a goalkeeping error from Stephen O'Keeffe saw them go down by 2-13 to 0-16 to Tipperary.
But Moore, who captained Galway for the past two seasons, said it is vital that Galway do not get too carried away with their facile opening weekend victory.
"Waterford were very unlucky against Tipp. They probably shot themselves in the foot with all the wides. It is always a very, very hard game against them."
The Turloughmore man added they were keen to build on the quality of their win over Dublin: "Dublin gave us a good hiding in the league last year so we knew it would be a tough game.
"But we're not going to get carried away. We've worked hard all winter and it's encouraging we've made a good start but we have to drive on from here."
