He could well be hiding what he really thought to protect the players that we already have (in which case good management) or he could be telling the truth that he is happy with squad of players he's got. I agree the team is stronger than it was before the window opened. We will only know the truth in years to come when his autobiography hits the shops.
I think his general demeanour was quite positive, usually under duress you might get an irritable person in front of the media but seemed happy enough to me. I would have told the first one to do one talking about Sissoko so much, so obviously didn't bother Ron too much.
