I think its a good move, more players for a team that Loves to put on that red shirt of pool will do wonders, fowler/carragher/gerrard 3 pasionate footballers at a team they love will always bring confidence to a club.
It doesnt matter if hes 30, or if anyone thinks he can still play at high standards, its players with a passion for the club that most teams miss nowa days.
I personally cant see him banging in 30 a season myself,but for a free transfer its all good.
