Sergio Gustavo Suárez Arteaga (born 6 January 1987) is a Spanish professional footballer who plays for Thai club Port F.C. as a midfielder. Born in Las Palmas, Canary Islands, Suárez came through local UD Las Palmas’ youth system, making his senior debut with neighbouring Castillo CF whilst on loan. Upon his return, he then spent one full season with the B-team, in Tercera División; on 14 November 2007 he made his first official appearance for the main squad, starting and scoring from a penalty kick in a 2–4 home loss to Villarreal CF for the Copa del Rey.
Over the course of the following six campaigns, with the club always in Segunda División, Suárez was regularly played, his first game in the competition taking place on 8 December 2007 as he came on as a 60th-minute substitute in a 1–0 home win against SD Eibar. On 15 May 2011, he was one of three players on target in a 5–3 success at FC Barcelona B which all but certified the team’s permanence.
Suárez was loaned to fellow league side CD Mirandés midway through 2012–13 and, when he returned to Las Palmas for the following season, was not even given a jersey number. He went on to spend several years in the Thai Premier League, starting out with Police United FC.
Suárez’s twin brother, Francisco, is also a footballer and a midfielder, and both played mostly for Las Palmas during their careers.
