Frederick John Callaghan (19 December 1944 – 13 September 2022) was an English professional footballer, who made over 290 appearances in the Football League for Fulham as a left back. After retiring as a player, Callaghan became a manager and coach, most notably in the Football League with Brentford. He later had a long career managing and coaching in non-League football. Playing career A left back, Callaghan joined First Division club Fulham as an apprentice in 1962 and made his first senior appearances during the 1963–64 season. His debut came in March 1964 during a 2–2 draw away at Aston Villa. As a player, he was described as "a tough-tackling defender who was not averse to crunching tackles and the occasional overlap down the flank" and was nicknamed "The Tank". By the 1966–67 season, he had broken into the starting lineup on a regular basis, but was part of the team which suffered a double relegation from the First to the Third Division in 1968 and 1969. Callaghan made a career-high 52 appearances during the 1970–71 season and appeared in 45 out of 46 league fixtures, helping the Cottagers to promotion back to the Second Division with a second-place finish. Although not a regular goal scorer, he scored a key goal in the 1971–72 Second Division season, securing a 2–2 draw at Charlton Athletic that saved the club from relegation. Callaghan made his final appearances for the club during the 1972–73 season and was forced to retire in 1974 due to a back injury. He made 336 appearances for Fulham across all competitions. Managerial and coaching career Non-League football Callaghan had a long managerial and coaching career in non-League football and held roles at Enfield, Woking, Basingstoke Town, Wealdstone, Carshalton Athletic, Walton & Hersham and Kingstonian. Brentford In February 1977, Callaghan joined Fourth Division club Brentford until the end of the 1976–77 season, as assistant to manager Bill Dodgin Jr. His arrival coincided with the team's sharp upturn in form, which culminated in a run of just two defeats from the final 18 matches of the season, which pulled the club away from the re-election places. After Dodgin Jr. was given a "leave of absence" in March 1980, Callaghan returned to Griffin Park as caretaker manager until the end of the 1979–80 season. After some positive early results, he signed a two-year permanent contract in April 1980 and managed the
