Glenn says that finding a winning formula on the road is vital as we head into the busy festive period.
Four out of our five games over the next two weeks and a bit are away from home - including the FA Cup third round. The boss knows that this run of games could well shape the season.
We head to Manchester City on Monday, face Charlton at home on Boxing Day, followed by a trip to Newcastle and a Premiership-FA Cup double-header against Southampton at St Mary's.
While the squad have taken a degree of confidence from the stirring performance against Arsenal, Glenn is attempting to guard against potential travel sickness.
"It's different circumstances because we're away and that should't make much difference, but we all know it does," admitted Glenn.
"We can go up to Manchester with a lot of optimism and belief about ourselves after the way performed. There are enough games in life when you don't get your just rewards, sometimes it goes the other way and you pick up a point when you don't deserve it, but we deserved to win it and it just didn't happen for us. Every game is different though and we've got to move on from there.
"We've also spoken this week about the fact that we've got five important games coming up in a very short period of time and four of them are away. We've got to look how we play away from home and how we can win matches. It's something that starts at Maine Road.
"We find ourselves with four games away now. Our last couple of away games, Birmingham comes to mind, along with Sunderland, where we haven't played well. "We've got to improve on our performance so we might be in a position to go and get the three points."
