Kevin Keegan, the former England international and manager known as "Mighty Mouse", has died at the age of 75 following a battle with cancer. In this tribute, Daily Mail columnist Oliver Holt reflects on Keegan as a footballing pioneer whose exuberant, emotional style and colourful personality stood out in an era of English football often characterised as grey and reserved.

Keegan enjoyed a decorated playing career before moving into management, and remained a beloved figure in the game right up to his death, with his final public appearance coming in Newcastle in May, where he drew hundreds of adoring fans despite his illness. Tributes have poured in from across football, including from Alan Shearer, who called him his "hero", Jamie Carragher, who described him as "one of the greatest players this country has ever produced", and Prince William, who said Keegan "inspired generations". Michael Owen also paid tribute, recalling Keegan's warmth and humour during their time together at Newcastle and with England.
