Australia coach Mickey Arthur has said he is not worried about former bowling coach Craig McDermotts presence in the Ireland squad,whom they face on Wednesday in their opening group stage match of the Twenty20 World Cup. The coaches don't play the game. He could pass on all that info that he liked, the Sydney Morning Herald quoted Arthur,as saying. It's like when hopefully we come up against [Arthur's former team South Africa deep in the tournament,the players still have to go out there. I'm just happy to see ''Bill'' back on the circuit. It will be nice to catch up with him, he added.
