Brazilian midfielder of Real Madrid Casemiro said his side's loss to Betis could cost the club the La Liga title this year.
“This could cost us the league. We have to think game by game. To win the league you cannot afford to play games at this level and today we did not play well – Betis were better than us,” he told reporters.
Real are the second in La Liga after losing 0-1 to Real Betis.
