Real Madrid will not give up on the LaLiga title despite suffering a further setback in a 2-2 draw with Celta Vigo on Sunday.
Madrid are 16 points adrift of leaders Barcelona following a result that extended their winless run on the road to four league matches - their worst such sequence since 2008.
Two goals in as many minutes from Gareth Bale put Madrid in front after Daniel Wass had given Celta the lead with a delightful lob.
But after Iago Aspas had seen his penalty saved by Keylor Navas, Maxi Gomez powered home a header to deny Madrid a valuable three points.
"Real Madrid never give up," insisted a determined Casemiro. "We believe in ourselves.
"It's difficult. We played very well in the first half, but in the second we didn't get out of our half.
"We had the chance to go 3-2 up [in the last minute] with Lucas [Vazquez], but this is football.
"You have to kill teams when you have the chance, because otherwise they will bite you.
"It was a difficult match, played with a lot of intensity.
"The two teams were playing well, but we have earned two points less.
"The gap is big now, we're further away and things are much more complicated."
Zinedine Zidane's side do have the comfort of three consecutive home games to come, with a Copa del Rey second leg against Numancia, before Villarreal and then Deportivo La Coruna visit in the top flight.
