Glen is staying confident despite Saturday's 2-2 draw, and says: "Glenn said it was a point gained after Bolton losing - but it could have been three points gained, so it depends which way you look at it.
"Villa are still in it, though, because they don't have an easy run with Newcastle and Manchester United, so we will have to wait and see.
"We will train the way we have been this week and my message to the fans is that I am still feeling confident.
"We will just have to beat Bolton, though I am not making that sound easy; we have got to win it."
And captain Joe agrees: "We have to press on now and prepare for Bolton because if we get a good result there it is game on - the results on Saturday actually went for us a bit, Bolton lost and that is a plus point.
"We are playing a lot better than we were and we are on a good run of form, although it would have been nice to pick up a couple of wins against Southampton and Aston Villa."
Glen could have covered himself in glory to give West Ham the three points when he burst through into the box only to see his shot saved by Peter Enckelman, and he says: "I nearly scored but the keeper has pulled off a 'worldie' to be fair. I thought it was too powerful for him and it was still going goalwards once he saved it but it was a good save.
"I didn't have time to look up and I knew I had a good chance so I just went for it.
"It was definitely two points dropped - we haven't created that many chances for a long while and another day they go in. Jermain is disappointed - everyone is.
"There were so many chances I don't know which ones to talk about. Lomy's early doors which hit the post and then the bar, a world class save from Fredi's one, Jermain has missed a few one on ones..."
So now the focus is on the trip to Bolton on Saturday and Joe adds: "Although it is a massive game it is not all or nothing as there will still be plenty of football to play - but we have to play well over the full 90 minutes.
"It will be the biggest match I have ever played in and we have just have to get the right result; with five games to go we know that we can pick up enough points to survive."
