From a media conference today, Lyon spoke of his excitement to lead the promising group at Fremantle.

“As a career AFL coach, I am incredibly excited to be appointed senior coach of the Fremantle Football Club and I look forward to the challenges that lay ahead,” he said.

Fremantle president Steve Harris said Lyon’s professional attributes and coaching style were ‘founded on a demanding work ethic highlighted by his professionalism, diligence and ruthless will to win’.

"It is clear that Ross can deliver a consistent and successful game style while, at the same time, continuing to build the culture of our playing group,” Harris said.

"We expect, under Ross's guidance, to execute a well-planned pre-season that will lay the foundation for a playing group that is consistent, driven and competitive throughout the entire home and away season and plays finals in 2012."
