Aberdeen won 5-0 against Daugava Riga at Pittodrie last week but the Latvians put themselves about during the game resulting in two red cards.
Their rough tactics led to Peter Pawlett missing tonight’s return leg, but Hayes has insisted he and his team-mates will ignore that and carry out a thoroughly professional second-leg performance.
Hayes said: "There were a few late tackles and they had two players sent off. I thought the one on Peter Pawlett was a straight red card anyway as it was off the ball.
"There were a couple of tackles on myself as well, but I am used to that and I thought we protected ourselves quite well.
"We kept our discipline and showed our maturity as well so we didn’t get drawn into any silly tackles.
"We want to win, we want to put in a good performance and build up our fitness as well."
