"Hopefully I will start against Slovakia but we will have to wait and see what the gaffer feels - I don't know for sure yet," he says.
Glen came on as a second half substitute for Stuart Parnaby in Monday night's friendly against Serbia and Montenegro, and helped the team to a 3-2 win.
Steve Bywater was also a second half substitute, on for the injured Rhys Evans, while Jermain Defoe, who started the game, scored England's second after having a goal disallowed earlier in the second half.
"It was alright, decent, they weren't too bad a side, and it is not going to be easy at that level anyway, is it?
"Steve couldn't have done much about the goal, and Jermain deserved two because he wasn't offside for the first one."
As for matters domestic, he admits he has preferred to concentrate on his England duties while he represents his country.
"We haven't really spoken about last season, we are just taking things day by day," he says.
"The disappointment of going down is still there, but there is nothing you can do about it - you can't change it now so there is no point getting the hump about it."
It will be but a brief break for West Ham's internationals, with preseason training due to start on July 1st, but Glen says:
"I am going to try and get a little break somewhere for 10 days or something; I'd like to be away now but I prefer playing for my country and there is only about another week to go."
