Glenn has declared that the team are determined to erase the memory of six points lost to Charlton last season when we travel to the Valley tonight.
We suffered a 3-1 reverse at Charlton in December and fell to a 1-0 defeat in March and Glenn feels that the team currently has the resilience and belief to buck this recent unwanted trend.
"They beat us twice last year and we're obviously going over there determined that doesn't happen again," said Glenn on Monday.
"That hurt us last season. We didn't perform particularly well, I remember, over there in the first 60 minutes and we found ourselves two goals down pretty quickly, making it an uphill struggle.
"We've now got four points out of a possible six and we're definitely going over there with a resilience and belief about us that we can get the right result."
The boss knows that getting results at the much improved and enlarged Valley is no easy task for any team.
"That crowd always get behind them, like at the old Valley. That club has transformed itself over the years and they should be proud of their club.
"They get behind their team superbly well and they remain patient with them. It's a hard game for us - it always is when you go to Charlton.
"Chelsea sneaked it over there, but they were having a hard time until things starting going for them. Charlton were down to ten men and Chelsea had a bit of good fortune.
"Charlton have now gone away to Bolton and shown their resilience with a win, so they'll now be keyed up waiting for their first home win."
