I don't have a problem with ex players celebrating. In fact it's become quite the boring cliche not to now. They pay his wages now and he's just bagged a screamer in front of a sizable contingent of family and friends who were at the game.
As long as they don't go over the top or rub ex supporters' noses in it a la Rory at the Shay in 06 (who didn't even get the goal himself by the way
)
To be fair to the Italian Accringtonian he made a special effort to come over an clap the travelling 98 at the end of the game.
It did however make the day worse as we all knew inevitably he'd pop up. Sod's law it's a wonder goal which proved to be the winner.
