The club signed David Connolly in the summer, followed by Nigel Reo-Coker, Jobi McAnuff, and Adam Nowland mid-season, and Alan says:
"We have taken four boys from there, three this year, and I have to say that all of them have been terrific people, not just players.
"I think that is important and it tells you a lot about the people that work there; they are obviously doing the right things in what has been a tough year for them - but we can't have any sympathy for them."
Stuart Murdoch's side are bottom of the division and somewhat adrift, but they have been forced by the administrators to sell most of their best players, - not just to West Ham! - and Alan says:
"I think he has probably had the toughest job of any manager this year, personally; he has had to just get on with it and done a super job to the best of his ability.
"They have a great tradition there and if anyone thinks we are going to run up a few goals they would be mistaken; it is going to be a tough game and I'd certainly settle for a one goal victory myself."
Alan is desperate to avoid the frustrations of Saturday's 0-0 draw against the Dons' fellow relegation strugglers Walsall and he adds:
"On Saturday it was a case of 'typical manager says he wants the fans to get behind his team' - and then his team put in a sub-standard performance.
"I am not the first that has happened to and I won't be the last but I hope they just turn up against Wimbledon and we give them something - they certainly deserve it after Saturday.
"We were really disappointing in the first half and the ball was out of play more than it was in.
"We lacked vision, we were over-eager at times, desperate to win, but didn't do it in the most educated way."
Alan is demanding the side comes out against Wimbledon playing at a high tempo and adds:
"That was where we fell down on Saturday; we tried something tactically and frankly it didn't work.
"I have to hold my hands up to that - I think it is important the manager does that - and I got it wrong.
"It is important that we are right for Tuesday and with Mattie coming back that will help."
