Stoke City boss Mark Hughes has enjoyed a pop at former Manchester United teammate Roy Keane.
Keane has never been forgiven by golfer Rory McIlroy for ignoring him as an autographing hunting youngster.
Asked about Pep Guardiola admitting he was a ball-boy when he was playing for Barcelona, Hughes said: "He probably didn't ask for my autograph. But I always give mine. I'm not Roy Keane! Sometimes you don't know who you're giving an autograph to. I remember David Beckham came up when he won a Bobby Charlton competition.
"This little kid came over and we had pictures together and lo and behold he became the player that he was. But I don't remember Pep."
