Real Madrid are still in the hunt to end the season with a silverware and Casemiro believes they are capable of competing in both competitions.
Zinedine Zidane’s men currently sit third on the La Liga table six points behind leaders Atletico Madrid. And are also in the Champions League quarter-final, having booked a date against Liverpool following a comfortable win against Atalanta in the Round of 16 tie.
The Los Blancos have had a stuttering campaign so far but Casemiro remains confident that Real Madrid can get the job done towards the business end of the season.
"Everyone knows what we are capable of, that we can do it," Casemiro said in an interview for TVE.
"We are going to fight until the end. We know that it is very difficult, but we will fight for both titles.
"For Real Madrid all games are important. We are already used to playing the big games.
"We like to play these type of games. First, we have to think about Eibar and then about the Champions League and the Clasico [against Barcelona]."
Real Madrid will be facing Eibar in the League on Saturday before entertaining Liverpool in the first leg of the Champions League on Tuesday.
"It will be a very beautiful match and it will be decided on details," Casemiro added.
"Whoever makes fewer mistakes will win. Liverpool have great players and this match could be a Champions League final.
"These are very nice games that all the players want to play. We have to give everything in all the games, not only against Barcelona.
"They are games that when you win, give you a lot of encouragement for the final stretch of the season."
