I was speaking to a close family member about this incident as he knows some high profile agents and this is what I've been told!
The bonding session was not just for players. Other people from other departments at villa went too.
Anyway, Dunne did have way too much to drink and was a bit Lippy about a few things. A guy who was from the I.T dept started to have banter with Dunne but turned into him taking the piss out of his cock up at wembley last year. Dunne kicked off, saying what the fuck do you know about football etc, it got a lot more heated and that's when Collins got involved! I'm led to believe Collins was playing peace maker but due to his involvement explains why the story came out as it did.
