Atletico Madrid have agreed a deal with Villarreal to sign Spain midfielder Rodri on a five-year contract.
The 21-year-old graduated from the Atletico academy before joining Villarreal in 2015 and last season he made 47 appearances for the Yellow Submarine, scoring once.
A statement published on Atletico's official website on Thursday said Rodri would officially return to Madrid on July 1.
Rodri made his Spain debut in March, appearing in the 1-1 friendly draw against Germany. He previously won the European Under-19 Championship with Spain in 2015.
