Glenn insists that while Sunday's final in Cardiff is a step in the right direction, he is building for the long term here at the Lane.
In his first full season in the job, Glenn has steered the team to the Worthington Cup final and the quarter-finals of the FA Cup. He says, however, that these are only worthwhile markers if they are won.
"That is my job, my priority," said Glenn on putting in the foundations for sustained success. "The cup is fantastic, to get to the final in the first year only if we win it.
"My job is to make sure that success is long-term. Fortunately I've got a five-year contract so I'll have another four years at the end of this season.
"There can be plans, there be demands and desires, if you like, that hopefully I can make and deliver."
With the Worthington Cup final and a ticket to Europe on offer so early in the season, Glenn assured that nobody at the club will be taking their foot off the pedal for the rest of the campaign if the trophy returns to the Lane.
"As the manager I can say that the last thing anyone at this club will be doing is putting their feet up, I can assure. If we did it wouldn't mean much more than getting into Europe and winning a trophy.
"Once you've had a taste of it you want it again.
"Also, if the result doesn't go well for us and we get dumped out of the FA Cup our season could be very quickly turned around in two weeks. We're all very much aware of that, so it's a big game for us.
"I said it and I'll say it again, the hard work for all at the club starts now, from now until the end of the season - and that means the league position as well."
