"Sometimes you need the kick up the backside similar to the one we had against Liege. You don't want to go into the season a little bit complacent, and no one could argue against the fact Liege were the better team on the night," said Gerrard.
"It was certainly a wake-up call for us, and the best thing about it was that we didn't get beat.
"We're still in the tie and know that at Anfield we will play a lot better. Liege will also find it more difficult."
