Barcelona striker Robert Lewandowski sees Sunday's clash with Atletico Madrid as a must-win.

Lewandowski says they must take advantage of Girona's recent stumbles.

He said: “Winning is very important for the team, mentally it's important for us. We have to go all out from the first minute.

“We must take a step forward. The season is very, very long and we want to win every game to retain the league.

“That's why we have to win and secure six points in the next two games against rivals at the top of the table. "
