Not really "needy", I personally couldn't care less, but it would help so that I don't have to explain to my boy why he didn't clap the supporters.
Then there is of course the question why wouldn't he?
He bemoans "...these are the moments when you need people behind you a little bit. I get sometimes why that might not be the case. When you see certain traits or certain things happening. I get human instinct, it is sometimes very difficult to do that (support).
"But I can't control the fans. We can't control the fans. We can help them along the way..."
A big part of gettings fans on your side is having a connection with them. All in it together. Clapping the supporters may well help to establish that, it's a small tiny thing that takes very little effort on his part, but means something to other people. So why not do it? It's just a courtesy thing and helps build a rapport between the team and the fans.
Some supporters look back at Woodgate positively, despite his obvious lack of tactical nous or long-term thinking, but he managed to build a connection with the fans despite mainly playing in front of empty stadiums! He did this as far as I can tell, by saying "up the cherries" in a post-match interview... that was it. Due to that some supporters were then willing to look past some of his limitations as a manager and they backed him.
Parker could do with some of that good feeling and he could get more with very little effort.
