Kevin Davies wouldn't have gone to Burnley or anywhere else if it had been his choice, once the club decided not to offer him a deal then he has to make the best move for him and his family. Burnley are a championship club and he won't have to move house, he may even get 2 years or an option for another year. Other offers may come if he waits but why should he not at least talk to the club.
The consensus of opinion on here is that he isn't good enough to play at this level and certainly not for us, so I really don't understand why anyone would be annoyed that may sign for Burnley. If he plays against us in August so what, he's past it right so effectively we will play against 10 men.
