Riera played for Mirandes for the past two seasons. His performance last season was particularly impressive, as he scored seven goals and provided four assists in 46 games.
Before joining Mirandes, Riera was part of the youth system at Real Betis. His experience and skills will likely benefit Real Oviedo in the future.
It's worth noting that Riera signed with Real Oviedo as a free transfer, meaning the team did not need to pay a transfer fee to acquire his services.
