"If they didn't have the result they wanted they have got to get focused on us getting the result we want - and looking at them training, I think they are," he says.
"We have a few bumps and bruises, and there were a couple of disappointing results from a couple of the lads.
"But they have to put all that behind them and all that counts for us is what they are doing when they wear a West Ham shirt.
"Christian is obviously very disappointed by Scotland's result as I'm sure are all the other Scotland players.
"But I would be the last person to comment on their performance; it would be wrong of me to talk about someone else's team.
"Gary Breen is disappointed by the Republic losing in Russia, but both have come back in good health and we will have to make sure that they do well when they play for us."
Equally, Joe Cole and Trevor Sinclair would have hoped to have had a better time on the international front; the pair, of course, only came on for England in the second half and Glenn adds:
"It doesn't make it easy; I'm sure both of the lads would have liked to have started but it wasn't to be.
"But they have both added another cap and are back to hopefully help us to the win we want."
Perhaps the happiest player to be involved in international action last week was Titi Camara, who scored for 177th ranked Guinea in a win over Liberia [ranked 81st].
He scored in their opening African Nations Cup qualifier on Sunday after 57 seconds in a game that marked Guinea's return to international action after they were expelled by FIFA last year following a row with the government over the independence of the national football association.
Closer to home and pondering on the fact that West Ham find themselves bottom of the Premiership in September for the third season in a row, Glenn admits he is perplexed.
"I don't know why it is; if I knew the answer for the last two starts we wouldn't have had the start that we had," he admits.
"It is very difficult to put a finger on it because I was happy with the way they trained in preseason and I was happy with their fitness.
"But we haven't picked up the results that we want - and we have to start doing that tonight."
