The Republic of Ireland under-21 international, signed in February 2002 from Barry Town in Wales for £75,000, reveals: "I have joined them on a three month loan until the end of July, and I have just signed today.
"I haven't played too many games in the reserves this season so Glenn got on to me a while ago and said I need to start playing some matches now, because the I have done well in the last two reserve games.
"He felt I needed a run of games and some match experience, so I am going to the summer League back in Ireland - the Eircom League has improved a lot.
"It was set in motion before Glenn fell ill, and then Derry City got in contact with the club because they got word from David Kelly, who is on the coaching staff at Tranmere, who had seen me play - and was playing with Derry City last year."
David knew it would be tough when Barry Town boss and former Hammer Kenny Brown agreed the deal with West Ham last year, but he insists he has no regrets.
"I always knew I had competition when I came here and Raimond Van der Gouw has played the majority of reserve games - I can understand where the gaffer is coming from on that as he sits on the bench, and needs to keep sharp," he says.
"Raimond is getting on a bit now, though, and it should leave the door open a bit for me and Steve Bywater, so we will see how it goes next year.
"I am still hopeful of getting into the first team, and I still have another year left on my contract.
"Hopefully this move will be of great benefit to me, then I will come back in August and hopefully I can then get involved.
"It all depends on where we end up next year, but I do hope we stay up because we all want to be involved in the Premiership."
David is confident that will happen, basing his assessment largely on the mood of the players at Chadwell Heath.
"We will just have to wait and see how it goes, but I firmly believe we will win the next two games - I really think it is between Bolton and Leeds now.
"There is still a good vibe in the camp and a good attitude with the players; they are all bubbling and buzzing, and the there are no heads that have gone down.
"You can see that from the results that we are battling hard and working hard, and Glenn did a lot of work before he got ill - so if we do stay up it will be a great thing for him.
"He always knew it was going to be tight coming into the last games of the season, so it will be interesting to see what happens."
Of his reaction when he heard about Glenn's illness, he says: "I was still back in London and I was very shocked because he seemed fine - it is horrific, really.
"Glenn signed me, he has done a lot for me and other young players, and I have got great respect for him.
"I think Trevor Brooking will do the business but, as Trevor said himself, it was all in place anyway; the lads knew what had to be done."
