Brewster was delighted with his side's display at Fir Park

"It's pleasing to get four goals and not concede," he told BBC Sport.

"We put Gretna under a lot of pressure early on, won a couple of corners and that's where the penalty came from - then we were up and running.

"People were talking about a relegation battle with us and Gretna but I've always got my eye on the team ahead of us not behind us."
