Galway United travel Garryowen tonight to face Limerick in what many are calling a must-win game.
United arrive at the Markets Field five points behind Limerick and 10th in the league, with just two games remaining.
They are a point behind both Sligo Rovers and St Patrick’s Athletic.
Keegan believes positive results will be required in both of United’s final games and when they faced Limerick earlier this season, there was little between the sides.
Speaking to the club media, he said: “We need to be aiming for a win, you would imagine it would put us in a good position heading into the final day, if we were to win.
“Ourselves, St Pats and Sligo Rovers all have games against difficult teams at the weekend. All we can do is focus on our own performance against Limerick.
“If we don’t put in a performance against Limerick, we can’t whinge about the teams around us not doing us any favours.
“I think ourselves and Limerick are two evenly matched teams. We were below par against them in the FAI Cup, they were below par against us in the league at Eamonn Deacy Park. If both perform on the night, it’s going to be an interesting game.”
Gary Shanahan (shin) picked up a knock in training on Thursday morning, but it is hoped that the winger will be fit for the Limerick game.
