While Ríos stresses that Spain's La Liga is the club's priority, they still hope to progress in the Europa League.
Levante lie second in Group L with six points from two games and their next assignment is at Twente, who they demolished 3-0 last week.
"Anything can still happen in the last three games," Rios said.
"Our priority is the Liga, but we will continue to give our all in the Europa League. In this team everything is always very clear.
"The key to beating Twente last time was taking our chances and we must do the same again.
"I'm happy with my two goals - I always want to score goals. In recent games I have had chances but not converted."
Twente have drawn twice so far and following their defeat at Levante must start winning if they are to remain in contention for qualification.
Defender Roberto Rosales accepts that the loss at Estadi Ciutat de Valencia has cut his side adrift.
"It was a tough game against Levante and in our own stadium we have to become strong to pull this off," Rosales said.
"Now our group has become a bit complicated, but we have to keep pushing on.
"Levante are great opponents, very strong at home and with some terrific players."
Twente are unbeaten in 12 European home games, including nine wins, since a 3-1 loss to Villarreal in 2011.
