The 22-year-old striker arrives at the Vitality Stadium after an impressive 2025/26 campaign in La Liga, where he scored seven goals and provided five assists in 34 appearances, including memorable strikes against Real Madrid and Barcelona.
Rodriguez came through the academies of Girona and Real Madrid before making his senior debut under Carlo Ancelotti in 2023.
After spells with Getafe and Elche, Rodríguez now joins Bournemouth to add competition to the club’s attack ahead of their first-ever Europa League campaign under new manager Marco Rose.
"It feels like a great privilege to be here. I've always wanted to play in the Premier League and now, on my birthday, that dream has become reality,” Rodriguez told club media.
"It has been a dream since I was a child. When my agent told me Bournemouth were interested, I couldn't believe it.
"Everything I've experienced so far has prepared me for this next chapter, and now I want to keep improving and show what I can do."
