started playing football from an early age. He began his career at amateur club Sv Sempre Avanti and played from 1979 to 1983 in the academy of Vitesse. Manager Leen Looijen gave him his professional debut on 13 August 1983 against FC Wageningen; the match ended in a 3–0 victory for Vitesse. Bos spent his entire playing career for Vitesse, making a total 369 appearances in 14 seasons with his club. After his playing career, Bos worked at Vitesse as youth coach, assistant coach and manager. He is therefore considered to be Mister Vitesse. In 2012, the south stand of the GelreDome stadium was named the Theo Bos Stand. Bos died on 28 February 2013 of pancreatic cancer, aged forty-seven. Following his death, a special remembrance to honour Theo Bos took place at Gelredome with around 7,000 Vitesse supporters. As of the 2012–13 season, no player will wear the number 4 shirt at Vitesse after the club decided to retire the shirt out of respect for Theo Bos, "the legendary number four". Dutch defender Jan-Arie van der Heijden was the last player to wear the number. In November 2013, his biography Het is zoals het is ('It is what it is') was published, written by journalist Marcel van Roosmalen. In 2015, a statue of Bos was erected outside of the training complex at Papendal.
