Club career
Georgetown University
After one season with the Timbers, he opted to play college soccer at Georgetown University for four years. In 2019, he scored 11 goals as he captained the team to its first NCAA National Championship. With a further five assists, he was named Big East Conference Midfielder of the Year.[8] Montes rejected multiple contract offers from the Portland Timbers during his collegiate career.[9]
In March 2021, Montes completed a trial with an undisclosed Premier League team who had been tracking him for several months. A month later, he opted out of pre-season training and notified Major League Soccer that he did not intend to play professionally in the United States for the 2021 season.[9] On May 20, his MLS rights were made available to other clubs following the expiration of the Timbers' ownership, and later picked up by the New England Revolution.[10]
Crystal Palace
On May 25, 2021, it was announced that Montes would join Premier League side Crystal Palace on a one-year deal, subject to international clearance.[11] He completed the move without being eligible for a British work visa, meaning he would have to leave the club temporarily on loan.[12]
Botafogo
On August 12, 2022, Montes signed a two-year contract with Brazilian Série A club Botafogo.[15] The move reunited him with Botafogo owner John Textor, who had previously overseen his transfers within his multi-club network, including Crystal Palace and Belgian side RWDM.[16]
Initially considered an unknown prospect, Montes struggled for playing time in his first season, making only three Série A appearances and totalling 85 minutes. He did not feature at all for the club during the 2023 campaign. On April 21, 2024, he scored his first goal for Botafogo in a 5–1 victory over Juventude, marking just the second goal of his professional career and ending a scoring drought of 1,146 days.[16]
RWDM Brussels
In the summer of 2024, Montes returned to RWD Molenbeek, which had since rebranded as RWDM Brussels, remaining within the multi-club network owned by John Textor.[17] In January 2025, Montes sustained an injury that ruled him out for the remainder of the season.[18]
