The boss was naturally delighted with the show put on by the boys as Bolton were put to the sword in a game containing several passages of scintilating football.
The crowd of 28,430 might have fancied a win but, after the closeness of last week's encounter, few could have expected such a thumping.
"It could have been more than six!" said Glenn. "Some of the football was exquisite with the passing and the movement.
"I felt we learned a lot more about them from our League performance against them than they did against us.
"Our movement was great and Darren Anderton, for me, epitomised our performance. He set the stall out and we took it on from there. With the ball and defensively he was magnificent tonight."
Yet again, the boys have reacted to a defeat with a resounding victory.
"The way we played I was very, very pleased - the passing, the confidence... What we've managed to do this season is when we have have lost we've bounced back with a victory straight afterwards - and I think that was significant.
"We're not going to get carried away. Fulham coming up will be a different game, we will not just be able to pick the reigns up. Football is not that easy. We will have to work extremely hard to get the points and it will be a different type of game against Fulham. We know that.
"There are times to enjoy your football, and tonight was a time for the fans, players and staff to enjoy what they saw out there. We're in the semi-final, no more than that, and we'll cast our minds back to it when the draw has been made."
Glenn looked back on the game after Bolton were hit for six in the Worthington Cup and said 'it could have been more!'.
