A left winger or a forward, his main assets were dribbling and netting ability. He spent most of his professional career with Betis (nine years) and also had a brief unsuccessful spell with Barcelona, greatly marred by injury.
Over the course of eight La Liga seasons, Cuéllar amassed totals of 111 matches and 17 goals.
Born in Villafranca de los Barros, Extremadura, Cuéllar made his debut for Real Betis' first team aged 18, in a 0–1 La Liga away loss against CD Logroñés on 4 November 1990, with the Andalusia side finishing the season last. He became an undisputed starter while in Segunda División and scored 14 league in 1994–95, as they shot straight from the second level into a final third place (on 25 September 1994, he scored a hat-trick in a 5–0 home victory over Sporting de Gijón); during the campaign, he also appeared in two friendly matches with the Spain national team.
In June 1995, Cuéllar signed a five-year deal with league powerhouse FC Barcelona. After suffering an anterior cruciate ligament injury during his first official game, a 2–0 win at Real Valladolid, he would feature sparingly throughout his two-year spell, as Barça won three trophies during 1996–97.
Returning to Betis in 1997 for 300 million pesetas, Cuéllar would be sacked by club president Manuel Ruiz de Lopera after the side were relegated at the end of the 1999–2000 season, under the allegations of "alarmingly low working performances". After two stints in the second level, both ended in relegation, he moved to Levante UD also in that tier, and was an important element in the Valencians' top flight promotion, but would only appear seven times during the following campaign mainly due to injuries.
Subsequently, Cuéllar played three seasons in Tercera División, two with CD Lugo and his final with Narón BP. After 15 goals in 2007–08, best in the competition, he retired from professional football at almost 36.
In June 2015, Cuéllar was appointed manager of CCD Cerceda in the Spanish fourth tier. Two years later he moved up one level to Segunda División B's FC Jumilla, being dismissed after failing to win a single match in eight.
