Aidan Keane, Son of Roy Keane and Theresa Doyle

Roy Keane is widely regarded as one of the greatest players the Premier League has ever seen. But he was also one of the most fearsome players in the game, as can be attested by several of his opponents and retired Norwegian footballer Alf-Inge Haaland.

Keane was voted 11th in a list of 50 hardest footballers in history, but he is quite the family man despite his tough reputation. He has five children with his wife, Theresa Doyle. One of them is a son named Aidan, who is a teenager now. It’s unclear whether he is following in his father’s footsteps into football, though.
