What did Manchester City's Tommy Hutchison do in 1981's 100th F.A. Cup Final at Wembley?

Tommy Hutchinson went from hero to zero by scoring the go-ahead goal for Manchester City and then 11 minutes later deflecting a free kick into his own goal. The game ended in a 1-1 tie, so he ended up scoring all the goals for the game. At the time, rather than use penalty kicks to determine the winner, the two teams played a rematch which Tottenham won.
