João Carlos Pires de Deus (born 6 November 1976) is a Portuguese retired footballer who played as a left back, and a manager. He is the assistant manager of Turkish club Fenerbahçe. Having played no higher than the second tier, he began managing at age 31 with the Cape Verde national team. He led Gil Vicente and Nacional in the Primeira Liga and was assistant to Jorge Jesus at several clubs. Playing career Born in Setúbal, de Deus spent several years associated to local Vitória Futebol Clube, joining its youth system at the age of 15 and making his senior debut in 1995. During his nine-year senior career, he never competed in higher than the second tier, and represented C.D. Beja, Seixal FC, Lusitano G.C. and F.C. Barreirense, before retiring with his first club Vitória at the end of the 2003–04 season, at only 27. Coaching career De Deus started working as a coach immediately after retiring, working with Vitória de Setúbal in the fitness department under José Couceiro and José Rachão; he also had a spell with G.D. Interclube in Angola, again as a fitness coach. His first job as a manager was with the Cape Verde national team, which he left after an unsuccessful qualification campaign for the 2010 FIFA World Cup; shortly before the tournament, he led the team to a goalless friendly draw against Portugal in Covilhã. In the summer of 2010, and without permission from the Cape Verdean Football Federation, de Deus was appointed at Segunda División B club AD Ceuta. He was sacked by the Spaniards before the end of the year, however, returning to Portugal and joining S.C. Farense, which he could not prevent from being relegated from the third level in spite of an incredible comeback. From 2011 to 2013, de Deus worked in Portugal's second tier, with Atlético Clube de Portugal and U.D. Oliveirense. For the 2013–14 campaign he was appointed at Gil Vicente FC, thus making his debut in the Primeira Liga. After a poor start to 2014–15, which saw the team lose the first three league matches, de Deus was relieved of his duties. On 6 October, he was hired by Sporting CP B on a one-year contract with the option of a second. He was sacked on 15 February 2017, after a 2–1 home loss to Varzim S.C. put the reserves into second-last place. On 21 March 2017,
