John "Ian" Porterfield was a professional footballer, and an experienced football coach who worked at both club and international level for almost 30 years. Up until his death, he was the coach of the Armenian national team.
As a player, Porterfield scored the only goal of the 1973 FA Cup Final as Sunderland memorably overcame the odds to beat Leeds United. As a manager, he has the dubious honour of being the very first manager to be sacked in the FA Premier League era, when he was fired by Chelsea. He replaced Alex Ferguson as manager of Aberdeen in 1986.
