Dango Ouattara proved the matchwinner with a first goal for the Bees as the hosts won 1-0 on Saturday.
Andrews later said, "I thought everyone who was on the pitch defended phenomenally well.
"They approached the game with a mindset that was determined, selfless - when you look at someone like Dango and how he performed without the ball, it was all about the team - you can achieve amazing things when you're all on the same page, and today we showed that.
"We nullified a lot of their strengths, where they want to play the game, and we pressed high really aggressively at times and looked dangerous from that structure.
"We restricted them to very few opportunities."
