Marques was unavailable for selection for Leeds during most of January 2010, as he was called up to host nation Angola's 2010 African Cup of Nations squad. The most high-profile games he was unavailable for was Leeds' 2009–10 FA Cup tie away to Manchester United and the away FA Cup tie to Tottenham Hotspur. Angola were eliminated from the Cup of Nations on 24 January, so Marques returned to Leeds. Marques incurred a small injury at the tournament, which kept him on the sidelines for a number of Leeds' matches. When he recovered, he never had a chance to play, even when the club was struggling to win a match for the last part of the season.
