It was during such a period that Les Ferdinand swept us into the lead, but a failure to capitalise allowed Derby to sneak back into contention with a Fabrizio Ravanelli leveller.
A stat flash from Sky revealed that we had some 28 attempts on goal - more than Blackburn in their 7-1 mauling of West Ham - but there were still some nervous moments in the second period before Gus Poyet's delightful effort sealed the points once and for all.
"I'm delighted with the way we played," said Glenn. "Some of the passing and chances we created - the only problem was the chances we were missing.
"We've got to put our clinical boots on when we create as many chances as that.
"I was pleased, but it is never over at 2-1, you always feel uncomfortable when you haven't produced the goals that you should have produced.
"But overall the movement, the football that we played, was very much in the traditions of this club and I was delighted."
Glenn admitted that there was always the fear that, not for the first time this season, we would not reap full reward for a sparkling show.
"If we'd have come off there and not won that game it would have summed our season up because we've been performing very similar to that and not won games. Fortunately tonight we've come off winning.
"Derby never gave up and at this level you cannot sleep. I thought our back three did excellently in that sense, we concentrated very, very hard. It was a hard game for them because of the concentration."

Glenn was purring at almost all aspects of the team performance against Derby, but insists that periods of domination and creation must lead to more goals on the scoreboard.
