Rodri became Pep Guardiola’s second signing this summer after Angelino’s acquisition.
The Spaniard earned a reputation as one of Europe’s most exciting prospects with his defensively minded style in front of the back four.
Rodri, after completing his move from the Spanish club to the English champions, said: “What City have achieved in the last two years has been amazing and I’m looking forward to being part of such a talented squad.
“It’s not just the titles they have won, but the way they have managed it, playing attacking football at all times.
“It’s a style that excites me, as do the Club’s ambitions.
“I can’t wait to start working with Pep Guardiola and my new team-mates and hopefully we can achieve great things together.”
Txiki Begiristain, City’s Director of Football, added: “Rodri has proven himself to be a hugely talented, young midfielder, who has all the attributes we are looking for.
“He works hard defensively, makes himself available to receive the ball and uses it well when in possession.”
✍️Done deal! Welcome to the Champions, Rodri 🔥
