This is a book about the development of football in the last half century. Changes in life are inevitable. So why not football? And I have witnessed many changes in the professional game, some good, some not so good.

In The Changing Game stellar manager Martin O'Neill offers his unique perspective on decades of footballing history. Bringing his sharp instincts and intellect through his tenures as a manager for Leicester City, Celtic and the Republic of Ireland, fans will enjoy the first-hand anecdotes of how to prepare for and play against the titans of the game. Martin explores every aspect of contemporary football at the highest levels, including how we deal with injuries, foreign influences on the British game, the changing roles of managers, coaches and agents and the effect of social media and wage structures on players.
