Leeds won their first FA Cup and Giles his second when they defeated Arsenal 1–0 at Wembley in 1972, yet again they missed out on the League on the final day of the season after defeat to Wolverhampton Wanderers. Sunderland and A.C. Milan beat Leeds in the finals of the FA Cup and the European Cup Winners Cup in 1973, rendering Leeds trophyless again. Jack Charlton's retirement in 1973 also left Giles as the most senior member of the squad. In the same year he started to combine his Leeds duties with a spell as player-manager of his country.
