Barcelona coach Ronald Koeman admits their clash with Levante is a must-win if they're to stay in the title chase.

Koeman maintains that they will fight until the very end.

"We are going to fight until the last moment to win the league," he said.

"It is not in our hands, but we cannot make any mistakes."

Koeman admitted that he started watching the match between Real Madrid and Sevilla, but switched off due to nerves.

"I saw the first 20 minutes of Madrid and then [turned to] Milan against Juventus because it makes me a little nervous to watch it," he said.

"I prefer to watch a different game and learn the result when it ends."
