The former Sevilla striker is on loan with Zaragoza from Segunda Division side Barcelona B.
And he is adamant the team can put the disappointment of last week's home defeat to Athletic Bilbao behind them as they seek to climb out of the bottom three.
Zaragoza were on the brink of a big step to survival when they led with 10 minutes to go - but two goals in the last 10 minutes by the Basque team changed that.
With a home game against Atletico Madrid following Sunday's match at Real Betis, Rodri told Zaragoza's official website: "We are psyched to get the six points.
"Now there is no use lamenting, we have to raise our heads and give our best in these two games to take the six points."
However, the 22-year-old - whose loan spell to Zaragoza has yielded one goal from four appearances - acknowledges it will not be easy to bring three points back from the match at Estadio Benito Villamarin.
He continued: "Betis are a great team and have had a great year. Getting the three points will not be easy, but we have to respond and do well.
"We have two very important games to stay in the First Division. We are all aware of the importance of surviving and we will give everything for Real Zaragoza."
For Betis, the position is brighter. A win will confirm their place in next season's Europa League.
However, the hosts may be without Chica, who felt a twinge in his right hamstring during training yesterday.
Although the 28-year-old full-back has not yet been ruled out by manager Pepe Mel, he is certainly a doubt for Sunday's contest.
