Explaining his thoughts, he says:
"We haven't got any options really; Grant McCann has got a medial ligament injury that will put him out until preseason, but hopefully he will have a good summer and be back ready for training on the 4th of July.
"Of the other young players, apart from Richard Garcia, who I have got confidence in, there aren't too many other that are ready to come into the team; I wouldn't put a youngster in unless I thought he was ready, otherwise it could become too much of a harrowing experience.
"At the end of the day it is important that we attack every game in the right manner and give ourselves every chance of taking points from each game."
Shaun Byrne, one of the players who might have hoped for a chance before the campaign is out, is still playing his way back after injury, and was one of just four players with any first team experience to play in the reserves midweek.
Glenn says:
"Shaun has had an interrupted season again; he is a very unlucky player who doesn't ever seem to be able to put more than half a dozen games together.
"But he did well in the reserves against Watford last week, and the one thing about him is that he always gives you 100%."
So the only change to Monday's starting line up is likely to be Nigel Winterburn for Vladimir Labant, and Glenn says:
"We are looking for a good home performance and hopefully a victory that goes with it, but we know that this will be an extremely tough game.
"Charlton have got an amazing record against other London clubs; you could argue that with their results in the capital they are almost the kings of London.
"It goes without saying that Arsenal are the championship team but purely in London Charlton's record is amazing.
"I think prior to losing against Arsenal, who are absolutely flying at the moment, they were on an unbeaten run of something like 10 or 11 games against London opposition.
"This is always a big fixture for both sets of fans and obviously with Alan's and Mervyn's connection with the club it adds extra spice.
"It has got the makings of a very good game and the important thing for us is that we get the performance and the result that we all want at West Ham."
A repeat of the scoreline between the two teams earlier in the season is unlikely, though, and Glenn says: "It to'ed and fro'ed in a manner that was probably great for the spectators but not fantastic for Alan and myself.
"I think we probably went through the full range of emotions that night in the 94 minutes of the game and them making it 4-4 in that fourth minute of injury time.
"I think both Alan and myself were both a little bit miffed that when you score four goals you don't take all three points."
More recently, of course, the Hammers have picked up maximum points in two games, and Glenn adds:
"It was a very good weekend over Easter, just what we needed; it was pleasing to get past last year's total with a point more and six games still to play, and it is vitally important that we pick up more points in these final six games to finish with a flourish.
"We set out at the start of the season to improve on last year's 42 points and now we will try to gather as many points as we can in the last half a dozen games."
Of the Ipswich game, he says:
"It was annoying to have allowed them to get back in at 1-1; it was a real messy, rotten goal to concede with the ball bobbing around the penalty box for an eternity before they scored.
"We had two or three chances to clear it and we didn't, and when it went in I thought it was going to be one of those days again, but fortunately Paolo Di Canio came up with one of those goals only he can score to angle the ball away with great technique before Jermain Defoe came on to tuck one away - as he so often does."
And, looking at the victory at Craven Cottage, he adds:
"The win over Fulham was very welcome and very deserved; David James had to make a save of quality early on, but apart from that I thought we held them well, I thought we looked more solid as a back four and didn't get the full backs haring forward and leaving gaps.
"Michael Carrick had an excellent game holding the centre of midfield and stopping Malbranque playing; we decided after losing those 10 games away from home not to be so cavalier, whereas at home you force the pace.
"We have tended to go away and play the same, and obviously it hasn't worked out, so we decided to have a more solid look about us and it certainly showed - especially in the second half, which I thought was an excellent performance.
"We changed the system, blocked them off completely, and didn't really give them a sniff or an opportunity to score, and as the away team I thought it was an excellent performance and a terrific result.
"John Moncur came on for 25 minutes and played a solid role in the centre of midfield, we put Joe out to the right, and that made it very difficult for them to break us down.
"But we certainly haven't given our fans enough to cheer about this year on our travels."
Glenn admits he is puzzled by Fulham's form and says:
"Jean Tigana has been allowed to spend an absolute fortune; money has not been an object, and it is a mystery to me that they are on the run they are.
"But with home games against Fulham and Leicester to come I am sure they can pick up the points they need, or, if not, I am sure there will be a couple of points waiting for them away."
