Glasgow head coach Eddie Woleckie Black
"This is as good a result as we've had in Europe"
"Glasgow have proved what a good side they are for a long time now and I'm not surprised they've made it though to the last 16.
"It will be a tough tie for us, but we'll prepare for it as professionally as we would to face any team and we'll focus on ourselves.
"The fact that I'm Scottish is not an issue. My responsibility is to manage Arsenal and I'll be trying to manage them into the last eight."
Glasgow had been level at 2-2 with Liege after the first leg in Belgium and were in control from the start on their rain-drenched Petershill Park pitch.
Aline Zeler turned the ball into her own net under pressure from Suzanne Mulvey as the striker chased a pass from midfielder Denise O'Sullivan.
The Women's Scottish Premier League champions doubled their lead on the half-hour mark as O'Sullivan volleyed home a cross from Sarah Crilly.
Crilly bagged the third goal soon after half-time with a superb 18-yard drive that flew into the roof of the net.
The visitors got a consolation goal in stoppage time, Tessa Wullaert shooting home from left back Faustine Cartegnie's low cross.
Glasgow head coach Eddie Woleckie Black said: "This is as good a result as we've had in Europe.
"The pressure was on us here, but after criticising the team for some aspects of their play last week I couldn't fault them tonight.
"It took a lot of effort, but we've beaten a very good side and it was a thoroughly deserved win."
