Roy Keane was the fierce heartbeat of Manchester United's midfield and their domination of the Premier League in the 1990s.
The tough-tackling Irishman joined from Nottingham Forest for a British-record fee in 1993 and was a leader in the United side, before becoming club captain in 1997.
His energy and fighting spirit inspired his team-mates to seven titles during his time at the club.

There’s nothing he wouldn’t do on a football field, so he expects everyone to do the same.
Keane had everything you’d want in a midfield player.
