The game against Spurs represented the first time Glen had enjoyed being part of a watertight back four since he broke into the first team, and he says: "It was good and the first time we have won by two goals for a long time - as well as a clean sheet, and we have to keep a few more.
"We got about them and whenever they got the ball we won it back - we were at their throats from the beginning.
"It was an important three points, although last season we would have been expecting to win games like that anyway.
"The way we played was like the way we played last season anyway so hopefully we can keep it up now."
One thing he does concede from that Spurs game is the admission that Teddy Sheringham's close range header that somehow flew wide in the first half was a let-off.
"If that had gone in it would have been a different game, but it didn't, so never mind," he says.
"We didn't go out there to defend in the second half, but we knew if we kept the clean sheet we would win the game.
"We could have had more in the first half, such as the one with Jermain which goes in on another day, but apart from that Sheringham chance they didn't look like scoring at all."
Glen agrees that the ref had no option but to book him for his foul on Matthew Etherington - and was equally right not to send him off when he tangled with Mauricio Taricco soon after.
"The yellow card was fair, but in the incident with Taricco I didn't do anything, really.
"He kicked me in the chest and I just pushed his legs away, though if it had been away and the crowd were giving it some, the ref might have made a different decision.
"Everyone on the bench from the far side thought I punched him in the face, but I didn't, I just pushed his legs away.
"He fell over and then his feet were in the air. He pushed them out and hit me in the chest, clearly on purpose and, as some foreigners do, he was rolling around like a little girl.
"I wasn't going to lose my head over something like that."
Glen hopes to keep doing enough to convince Glenn Roeder he is worthy of his place ahead of last season's Player of the Year Sebastien Schemmel, and adds: "He is a good player but as long as I keep playing the way I have been I hope to stay there."
Glen may find himself up against Duncan Ferguson at the weekend, with the Scottish striker coming back to fitness, but he says another win would be a real confidence booster for the run-in ahead.
"The mood is good and if we can get a third win on Saturday it will get even better," he enthuses.
