Despite West Ham moving up to third place with a win over Reading on Saturday did not appease all of West Ham's critics, one or two of whom are claiming the front pairing - or, rather, the diminutive two thirds of it - don't pass to each other.
That they had scored all of West Ham's goals this season until Saturday seems to be overlooked, conveniently perhaps, but then the man whose opinion really counts, Trevor Brooking, says there are no problems.
"There was a question about that on Saturday but goalscorers do get their head down near the goal and go for it," he explains.
"There have been a couple of occasions when I have said to them one could have fed it to the other to square it across and it doesn't matter who tucks it in then.
"But it is a balance between the two and you don't want instinctive goal scorers to just keep knocking it off all the time - you have got to take responsibility.
"But they will keep working and get plenty of goals if they keep doing as they are."
"I am getting on very well with Jermain as I am with all the lads," adds David.
"We are both goalscorers and there are sometimes when I think Jermain could put me in - and he scores a great goal.
"Sometimes I shoot and he thinks he might be in but those are the decisions you make as a striker.
"There are plenty of opportunities when we have worked in tandem and it has worked well."
With Neil Mellor working unselfishly in the front three as well, it appears that Trevor has found the right formula for the time being - even if the strike force were frustrated on Saturday.
"At the moment the system Trevor is using is working very well; I felt at Ipswich I was getting chances further up the pitch whereas against Bradford the chances didn't seem to be falling to me because I played in that hole which I don't mind doing - but I am a goal scorer."
Still, like a great fisherman, David does ponder on the ones that get away, and adds:
"I had one disallowed at Portman Road and there was an offside I thought was unfair, and in the game before I thought I deserved one.
"But it doesn't matter who scores and that win at Ipswich as well as the one against Reading were great results."
