Rodri believes this season could still be the greatest in Manchester City's history.
The Spanish midfielder thinks securing the Champions League and FA Cup, on top of the Carabao Cup and Community Shield already won, would eclipse City's domestic treble of last season.
Those are now the targets keeping City focused after surrendering their Premier League crown, following a two-year reign as champions, to Liverpool.
The 24-year-old said: "We have two trophies already, we are fighting for another two, and this could be an unbelievable season for us if we win those two – it will be the best season this club has ever made.
"We want to fight. This is not over. We wanted to win the Premier League but we couldn't, so it is OK, we are going to fight for the others."
Rodri says City have already started thinking about reclaiming the Premier League next season.
City laid down a marker when they thrashed Liverpool 4-0 at the Etihad Stadium on Thursday – a sobering night for the Merseysiders in their first match since ending their 30-year title drought.
Rodri said: "I think the mentality of the boys was that we started next season on Thursday. We need to start right now if we want to fight for the next one."
City are back in action on Sunday as they travel to Southampton, who have won two of their three matches since competition resumed.
Rodri said: "You have to study all the teams – they have a very good team.
"But for us it is not important who we face. We play every game in the same way.
"We want to play forward, score goals. It is important in the next six Premier League games to stay fit so when we play important games we are ready."
Rodri is coming to the end of his first season at City after a £62.8million move from Atletico Madrid last summer.
He said: "It is a great experience where I have learnt a lot. It is the dream for me, I love the Premier League.
"Everything for me has been amazing this season and I am so happy with the decision I made."
