Rodri has admitted Manchester City's exit from the Champions League felt "like a war".
City blew a two-goal aggregate lead against Real Madrid to miss on the final against Liverpool in Paris on May 28.
"It was like a war, a big, big battle in the brain," Rodri told BBC Match of the Day. "You keep thinking about what happened. It's tough. You wait eight months for the moment to arrive and then, in the last minute, it is gone.
"The defeat to Real Madrid was so, so big but football is like this. You have to switch on the focus for the Premier League because it is even more difficult.
"We did brilliant today and we have to keep going. We expect nothing from Liverpool and we have to keep going. We have three finals and have to finish the season like we deserve."
