NO. That was the rumour at the time, as I said, if he wanted to move to Castleknock, nothing would have stopped him. He never (as far as I know) wanted to move to Castleknock.
There seems to be some people with a particular knife to grind on young Micheal. He was born in Dublin, went to primary school (for a time) and all of secondary school here in Dublin. He moved to Ashbourne temporarily some years back. He's now back in Dublin. His dad played for Dublin, he wants to play for Dublin as there lies his heart!!! I can't see why this is brought up time and again, unless there's an ulterior motive?
