For example, our legendary goalkeeper Peter Schmeichel won the Premier League title with the Reds and two decades later had the thrill of watching his son Kasper Schmeichel achieve the same feat with Leicester City.
But from a United point of view, John Aston Snr and John Aston Jnr went one better as both men won championship medals with the club.
