Manchester City have agreed to sell Rodri for a fee of £65.4m (€76.5m) to Barcelona.
City had been trying to convince Rodri to stay and sign a new contract.
But the midfielder made it clear he would prefer to move back to Spain this summer, despite having one more year left on his contract.
Rodri is expected to sign a four-year contract with Barcelona.
For Barcelona, they are parting with big money for a 30-year-old midfielder.
But Rodri has just guided Spain to the World Cup and Hansi Flick believed he could bolster the squad that won the LaLiga title this year.
