While naturally disappointed about the outcome against Blackburn, the boss looked to draw a positive out of the Worthington Cup final setback.
"We're bitterly disappointed in there of course," said Glenn. "There are a lot of players in there that have experienced losing in finals before, for some it is the first time. I've said to them that we've still got an opportunity to come back here again.
"Maybe by losing in this manner it drives us on and gives us an extra desire to come back again. We've got to look at something positive."
Glenn's next objective is turning the player's minds away from cup final gloom and on to Premiership matters at hand, starting with Sunderland on Saturday.
"We'll have to get this out of our system and that'll take a week and next week we turn our minds to the next game. At this moment in time I'm not enjoying the joys of life - but we'll live to work for another day, if you like.
"We could have averted it. The first goal maybe we couldn't, the ball was going for a goal-kick. The second we could have cleared quite easily.
"We had the opportunities to bury the game. Les' one on one, Gus has hit the bar. Les had two headers from five yards, the penalty decision went against us and I think that sums it up for us.
"We never got ahead of the game, we never got ourselves 1-0 up or 2-1 where maybe we could have flowed like we have this season.
"Credit to Blackburn, they played well and gave it their best."
Glenn insists that the losing experience at the Millennium Stadium should drive the players towards securing a repeat visit in May.
