But he also pays tribute to caretaker manager Trevor Brooking, who will be in charge for the foreseeable future until Alan arrives to take his first game in charge against Burnley on October 18th.
Reacting to the news that an agreement had been reached allowing Alan to take over as West Ham manager next month, David says:
"Trevor Brooking has obviously done really well since taking over as caretaker and you can't argue with a fantastic record - the lads have performed well under him.
"So Alan is taking over a club in a good state of mind and a good position, rather than a few months ago.
"I spoke to him in the summer and he was very impressive and forward thinking - you can see that by his results and the way his team plays.
"He has moulded them into a useful side where every player knows his job and I am sure he will continue in a similar vein here.
"It is difficult to say, because I have not worked for him but he was impressive when I spoke to him and his record at Reading speaks for itself.
"He obviously knows what he is doing and I hope we can continue on the way we are going at the moment."
But despite the manager's situation being resolved, David is still smarting about the decision to give him a yellow card - his fifth of the season - on Tuesday.
Recalling the incident, he says:
"I was just chasing down a back pass which didn't look like it would reach the goalkeeper and he came to the edge of the area.
"I tried to put the brakes on to stop myself and it was quite slippery on top so I slipped and it was a combination that and of him clearing the ball which wiped me out.
"Unfortunately I got booked for it which I can't really understand; if I had got the ball just before the goalkeeper he would probably have been sent off.
"But I got a yellow card which was disappointing; it was there to go for and he clattered into me not the other way round.
"The referee said he might have a look at it but I don't think he can rescind a yellow card, though he said if he made a mistake he would have a look at it so fingers crossed.
"It is disappointing; it is a league game and you want to play in all the league games, and particularly what will be a good game against Crystal Palace - but hopefully it will be overturned, so we will see."
As for the fact that he is now on six goals for the season, he says:
"It doesn't matter who scores; we all want to but it also would be nice if everyone was scoring so if maybe the front lads aren't scoring other people are chipping in.
"Christian scored against Reading and Matty scored a great goal the other night, which is really good to see. "I am sure we will see more goals going from around the pitch soon."
He reiterates that there is no problem with strike partner Jermain Defoe, despite media claims, and shrugs:
"There is no need to go over that one again, I think we linked well the other night and it is a shame he didn't score."
Looking at the weekend action in the light of Tuesday's confidence-boosting performance, he says:
"It was a good result at Crewe and although the first came on a weak back pass, on the play I thought we deserved to have some sort of lead at half time.
"As for Gillingham, they will be up for it, it will be a full house, and they will be throwing everything but the kitchen sink at us.
"We will have to deal with it and I must say the defence, midfield, and Jamo have been playing fantastically, though they don't need me to tell them that."
