Real Madrid extended their lead at the top of La Liga to five points, as they won 2-1 against Athletic Bilbao on Saturday.
Karim Benzema scored the first goal of the game as Cristiano Ronaldo found space down the left and he crossed for the France striker to put it past goalkeeper Kepa Arrizabalaga.
But, after Keylor Navas had made a wonderful save from Inaki Williams, the Spaniard powered home after a good knockdown from Raul Garcia.
However, Casemiro struck back within a few minutes as Ronaldo flicked the ball on at the near post from a set piece to slot home the winner.
Barcelona can close the gap again when they face Valencia on Sunday.
