Nuno Miguel Frechaut Barreto (born 24 September 1977), known as Frechaut (Portuguese pronunciation: [fɾɛˈʃo]), is a Portuguese retired footballer. A defender or midfielder, he could occupy a variety of positions.
Born in Lisbon, Frechaut emerged through Vitória de Setúbal's youth ranks, making his first-team – and Primeira Liga – debuts in the 1996–97 season, at the age of 19. He went on to represent Boavista F.C. until December 2004, winning the national championship for the latter in 2001 whilst appearing mainly as right back.
After a failed Russian experience with FC Dynamo Moscow, Frechaut joined S.C. Braga in January 2006. In very late August 2009, after three further full campaigns of regular use (an average of 22 games, with two UEFA Cup qualifications), he left the Minho club and Portugal, agreeing to a three-year contract with French Ligue 2 side FC Metz.
In August 2012, after appearing rarely for Associação Naval 1º de Maio in the second division, 35-year-old Frechaut returned to Boavista, reuniting with former teammate Petit at the third level team.
He was part of the nation's squads at both the 2002 World Cup – where he played and started in the national side's only win in the competition, the 4–0 against Poland – and the 2004 Summer Olympics.
