His Managerial career
after retiring from playing, he became a coach at Crystal Palace and then later QPR. In 1983 Graham was appointed manager of Millwall, and then his old club Arsenal in 1986. Arsenal hadn't won a trophy since 1979, but Graham turned the club around quickly, winning two League Championships, two League Cups, an FA Cup and the European Cup Winners Cup in eight years, making them one of the dominant teams of the late 1980s and early 1990s.
However, his tenure at Arsenal ended unhappily. Graham was sacked as manager of Arsenal on February 21, 1995, after it was discovered he had taken £425,000 in illegal payments from Norwegian agent Rune Hauge in order to sign two of Hauge's clients: Pål Lydersen and John Jensen. He was then banned from football for a year as punishment from the Football Association.
George Graham's return to football management came with Leeds United in September 1996. Although Leeds scored fewer goals than any other Premiership club (28) they still finished in a secure 13th place. 1997-98 saw Leeds finish fifth in the Premiership and secure UEFA Cup qualification.
