Roy Keane, Paul Scholes, Cantona and Beckham. There are others like Ruud and Neville and Ferdinand, but Roy Keane has to be the number one choice simply because he brought to the team. If you didn't do your job (you could be Beckham, Ronaldo, Ruud or any others at that time) you would know about it, either on the pitch or in the dressing room. He wasn't scared of upsetting the big names because it wasn't the name or salary that counted for him, it was how we performed as a team. He wanted more than 100%, he wanted every player to play as if it was a cup final. No other Manchester United player had that aura. I don't mean to be rude, but over the last few years, we have been captained by fannies i.e. Wayne Rooney who cannot be compared in any way shape or form.
