About Raya2

Club Raya2 Expansión is a football team that will play in the Liga de Expansión MX as of the 2021–22 season, it is the official reserve team of the C.F. Monterrey.

In 2020, the Ascenso MX was converted into Liga de Expansión MX this with the aim of turning it into a league for the development of footballers in exchange for financial support to member clubs that were in financial problems, due to this the possibility was opened for Liga MX clubs could establish their own teams in this league. However, in the first season of the new league only two clubs established secondary squads in the new league: C.D. Guadalajara with C.D. Tapatío and Club Universidad Nacional with Pumas Tabasco. While clubs like Monterrey preferred to lend their players to teams like Cancún F.C., Atlético Morelia and Alebrijes de Oaxaca.

Finally, for the 2021–22 season, the club's board decided to found its own team to retake players who were outside the club and give them the opportunity to reach the first team, so on June 21, 2021, the creation of the new one was made official team which was called Raya2 Expansión. On June 22, 2021 Aldo de Nigris was appointed as the first team manager.
