Mullery was
Brighton & Hove Albion manager between 1976 and 1981, and took the club from the third tier to the top flight of English football. When Mullery was appointed manager of Brighton's biggest rivals
Crystal Palace in 1982, it prompted anger and a short-lived boycott from some of the Palace fans. Mullery became
QPR manager in 1984 and guided the club to a 7–0 aggregate win over
KR Reykjavik in the 1st round of the 1984–85 UEFA Cup, but he was then involved in an extraordinary 2nd round UEFA Cup tie against
FK Partizan. In the first leg, which was played at Highbury because of UEFA's ban on the artificial plastic pitch at
Loftus Road, QPR beat Partizan 6–2, despite being 2–1 behind at one stage and down to ten men after QPR defender
Warren Neill was sent off. In the second leg, Partizan won 4–0 in Belgrade to win the tie on away goals. Partizan's victory was only the second time in the history of European competition where a team has overturned a four-goal first-leg deficit. Mullery's QPR side were also involved in an extraordinary home league match in September 1984 against Newcastle United. At half-time Newcastle were 4–0 up after a hat-trick from
Chris Waddle. But QPR came back after the break to draw the match 5–5. Mullery was sacked after six months in charge at Loftus Road just hours after QPR had beaten
Stoke. In 1985, Mullery said that his time at QPR "turned me into a monster". He suggested that the players couldn't overcome their disappointment that
Terry Venables had left the club. Mullery blamed what he called "the moaning, groaning bunch of players who treated me, themselves and their profession with contempt" for killing his love of football. After leaving QPR, Mullery stayed out of football management for 18 months until the summer of 1986, when he took over for a second spell as manager of Brighton. He lasted seven months before being sacked in January 1987. Mullery said of his sacking by Brighton: "You love the game, then it kicks you in the guts." In the early 1990s, Mullery coached
ATM FA in the
Malaysian Premier League. He later served
Barnet as Director of Football during 1996–1997. Mullery had a brief stint as manager at Sussex non-league side
Southwick F.C. He has worked for a number of years as a pundit for
Sky Sports, and in September 2005 also briefly took a role with Conference club Crawley Town as a 'football consultant'. ==Personal life==
