As the European champions, Manchester United faced off against Estudiantes de La Plata, the South American champions, in the 1968 Intercontinental Cup. Estudiantes won the series after a 1–0 win in Buenos Aires's "La Bombonera" and a 1–1 draw at Old Trafford. This became the first, and so far only, time Manchester United failed to win a title contested at their home ground. In the European Cup, United lost to Milan in the semi finals, after a Law goal that clearly crossed the line was disallowed in the second leg at Old Trafford, leaving United 1–0 winners on the night but 1–2 losers on aggregate. The season ended with Busby moving on to become General Manager. He had announced his intention to resign as team manager on 14 January 1969, and trainer Wilf McGuinness agreed to take over control of the first team.
