With the return of David Forde to fitness, the keeper, who made his second string debut against Wimbledon recently, is not included in the reserves' party to face Charlton.
But he was happy with his performance, and says:
"It was good; I kept a clean sheet, but it was never going to be a football match against Wimbledon, they just battle.
"It was nice to get the experience; hopefully I can be on the bench a couple of times at least and get a game somewhere.
"I feel much more experienced than last year; I want to improve little things and generally get better at everything."
Glenn, a third year scholar who turned 19 yesterday, says he is just playing his own way as he aims for the top.
"I have never really had a hero, I'm just thinking of my own game - it's a long road but hopefully I will get there in the end."
As for the first team's plight at the foot of the table, he adds:
"We have had a few hard games; it would have been nice to start well as we always seem to finish well."
