Tommy Marqués was born on 30 October 2006 in Barcelona, Spain. He came through La Masia and was promoted to FC Barcelona Atlètic in 2025 ahead of the senior season, having captured the attention of senior staff and analysts as one of the academy's most polished holding midfielders.
In April 2025 Barcelona announced a contract extension through summer 2028 with a €20 million release clause that rises to €25 million if he makes five senior appearances. He has since worked his way into the senior squad's matchday picture, with a small handful of La Liga and cup minutes during 2025–26 while reportedly turning down Premier League interest to stay on the Camp Nou pathway.
A tall, technically polished defensive midfielder, Marqués functions as a deep-lying playmaker — comparisons to Sergio Busquets are common in Spanish football media — combining defensive solidity with calm distribution. In June 2025 he was named in Spain's UEFA European Under-19 Championship squad in Romania, played three matches, scored against Germany, and reached the final, where Spain lost to the Netherlands. He projects as a long-term first-team midfielder if his development trajectory holds.
