Manchester City has signed Rodri from Atletico Madrid for a club-record fee after activating his reported €70million (approx. $79 million) release clause.
Atletico announced Wednesday the midfielder's exit clause had been deposited at LaLiga headquarters by Rodri's lawyer and City representatives, freeing him from his contract.
The Premier League champions then confirmed Thursday that the Spain international has signed a five-year deal, becoming their second arrival of the week after fullback Angelino was brought back from PSV.
Rodri's move eclipses the €66.9million (approx. $75.4 million) City paid to sign Riyad Mahrez from Leicester City in July 2018.
Rodri, 23, joined Atletico from Villarreal only a year ago, signing a five-year deal at the Wanda Metropolitano.
He made 47 appearances in all competitions as Diego Simeone's team won the UEFA Super Cup and finished as runner-up to Barcelona in LaLiga.
He also established himself as a mainstay on Spain's national squad, with many viewing him as the long-term successor to Sergio Busquets in holding midfield.
Rodri will be expected to provide competition for Fernandinho, while further strengthening the midfield options for Pep Guardiola's side.
