During his time at Osasuna, Munoz scored seven goals and provided five assists in 36 games, impressing Liverpool with his performance. The teenager can play on both wings and has signed a six-year deal at Anfield.

However, Munoz has aggravated a muscle problem that he picked up in the lead-up to the World Cup, which may affect his chances of playing for Spain again. He made his international debut in March and underwent a medical examination in Chattanooga before joining Liverpool.

A statement from the Royal Spanish Football Federation's medical team said that Munoz's injury will delay his return to competition, and his availability for upcoming matches will depend on the evolution of his symptoms.
