He had cocked it up in the first game at the Amex versus Palace. He got his tactics wrong and he underestimated how important that game was to the fans. At that time he had it in his head that Southampton were the team he wanted to beat, not Palace. I believe he acknowledged that he underestimated the importance of the Palace game.
I don't buy this at all. Why would it matter to him who we were playing? He would want us to win every game, surely? I don't believe for one minute that any manager would think "well this isn't our biggest league game of the year so I won't put too much effort into the tactics etc". Palace were the better side on the day and they beat us. I'm sure he tried just as hard to win that game as any other league game that season. I can't see where any underestimating the importance of the game is. You don't get any more points for beating for your rivals. Derby games are for the fans, not the management.
To sum up your entire career in one lucky win against Man City is grandstanding. Its deliberately provaocative, and you dicks are so far up his arse you cant see you've been jilted and disrespected, not just by this statement but by all his behaviour at the end.
If you are actually for real then I honestly think you need some professional help.
