Rui Marques is a former Angolan central defender who was born in Luanda, Angola on 3rd September 1977. Marques began his career at Benfica, but was released without breaking through to the first team. He spent the 1998/99 season in Switzerland with Baden, before moving to Germany in 1999 with SSV Ulm. Marques subsequently moved to Hertha the following year, but made just a single appearance for the Berlin club. Marques joined Stuttgart in 2001, initially on loan. He spent four years at Die Roten, but usually found first team opportunities hard to come by. In 2004 Marques joined Maritimo, but once again struggled for playing time.
In the summer of 2005 Marques was one of many players who went on trial with Harry Redknapp’s Southampton. He was not offered a deal at St Marys, and later trained with Ipswich before eventually signing for Leeds. Marques played just a single game for the Elland Road club in 2005/06, in the Carling Cup win over Oldham on 23rd August, where he looked slightly uncomfortable out of position at right back. He was loaned to Hull later in the campaign, but returned having played just once after injuring himself. Marques was part of Angola’s 2006 World Cup 23 man squad, playing in group matches against Mexico and Iran.
Marques finally earned a spot as a Leeds United regular in January 2007. Despite some impressive performances the Angolan could do nothing to stop the Whites from dropping down to League 1 in April. Marques was a key part of the Leeds side that reached the play-off final in 2007/08, despite a 15 point deduction. He scored his first goal for the club on 18th August 2007 in a 4-1 win over Southend. Marques lost his place in the Leeds side late into the 2008/09 season following the arrival of Sam Sodje on loan. He barely featured at all in 2009/10, with the arrival of Leigh Bromby pushing him even further down the pecking order. In May 2010 Marques was released from the club. He had been Leeds longest serving player before his departure.
