A mainstay of the great Manchester United teams of the 1990s and 2000s, Roy Keane is a player still held in high regard by the Old Trafford faithful despite a rather acrimonious exit.
The robust midfielder has taken his no-nonsense attitude into management and as a TV pundit, and fans enjoy his direct approach compared to many of his frothy counterparts.
Signed by Sir Alex Ferguson from Nottingham Forest in 1993, Keane picked up seven Premier League titles, four FA Cups and a Champions League medal before departing for Celtic in 2005.
But when picking his best ever United XI from his time in the red shirt, he left out a few big names leading some to suggest he might be holding grudges against some of his former colleagues. Ryan Giggs, Paul Scholes and Gary Neville were all overlooked by Keane
He shared his selections with Arsenal legend Patrick Vieira, a man he enjoyed a fierce competitive rivalry with during his playing days. Years on, the pair have a healthy respect for each other but that wasn't always the case on the field - or tunnel for that matter.
When asked about leaving out Giggs, Keane explained: "Having a great career doesn't mean you are a great player - there's a big difference. I'm not saying Giggsy wasn't (great), but do I leave out Ronaldo, one of the world's great players? Do I leave Becks out?"
"You don't win titles by having choirboys in your dressing room. Did Beckham challenge the manager? And it doesn't mean you are challenging the manager if you marry a certain woman - far from it."
Keane's Manchester United XI: Peter Schmeichel; Paul Parker, Jaap Stam, Gary Pallister, Denis Irwin; Paul Ince, Roy Keane, David Beckham, Eric Cantona, Cristiano Ronaldo, Ruud van Nistelrooy.
