The boss was naturally delighted that the team overcame a side that have become experts in winning away from home, one that was chasing a seventh win on the trot away from Anfield.
Glenn feels that the fact Liverpool very much needed another win allowed us to almost play them on the break.
"They were going for their seventh away win on the trot," said Glenn. "Normally they suck you in and hit you on the break with the pace that they've got.
"We spoke about that before and there were times when we were on the attack that might have happened. Today their mental approach was different, they had to come here and win and they attacked us - Hamman got more forward than I've ever seen him.
"It allowed us to break on them a little bit and capitalise on the space.
"Our football in the second half was exquisite at times, there was some lovely football played - stuff that we managed to achieve for the first four or five months."
Glenn added that, on the day, maybe Liverpool just met their match and that the result is encouraging for the seasons ahead.
"There's nothing much wrong with Liverpool, going for their seventh away win on the trot. They just came across a side that was equal to them in the first half and, I thought, in the second half was better than them.
"At the end of the day, we took the chance and they didn't take their chances - I think that was the dividing line between the two teams.
"What it proves for us is, we've not been truly out played or hammered by any of the top four or five teams, and we're getting closer to them and beat Leeds a few weeks ago.
"There's optimism in our camp that we can actually bridge that gap over the next two or three seasons."
Glenn described some of our second-half football as 'exquisite' as he reflected on a win over Liverpool in our final home match of the campaign.
