Winger Borja Sainz has left Norwich City and joined Porto for £14.25m.
The 24-year-old has signed a five-year deal with the 30-time Portuguese champions following a two-year spell at Carrow Road.
Sainz was the club's top scorer last season with 18 Championship goals despite missing six games through suspension as a result of a spitting incident.
The Spaniard joined the Canaries from Turkish side Giresunspor in June 2023.
City's sporting director Ben Knapper told the club website: "During his time with us, his performances and impact have been brilliant. He gave us all many memorable moments, scored some spectacular goals and was often the deciding factor in many of our games.
