Hansi Flick wants a swift response from Barcelona after back-to-back defeats.

Barca went down 2-1 to rivals Real Madrid in El Clasico on Sunday.

The Blaugrana had started their LaLiga campaign with nine straight wins. Had Barca won, they would have become the first team on record to win 10 successive matches at the start of a season in Europe's top five leagues.

Flick, meanwhile, is waiting on his 100th Barca win, with the defeat to Madrid coming after a Champions League loss to Paris Saint-Germain.

And the German now wants to see a strong reaction from his team.

"Of course, we have to improve. After this defeat, we have neither arguments nor excuses," Flick said.

"We will talk in every training session. I'm not worried. Two defeats are too many for me and for the fans; we don't want to lose.

"Now it is important to analyse and react. For me, it is clear that we have faced an opponent with great quality, who have been perhaps better than in previous Clasicos, and we were not fresh enough.

"We have to recover well, train very well and respond to this defeat. It's not all bad when you lose, and the road is very long until the end of the season; these things happen.

"We lacked a bit of luck; they also did well. We lacked freshness, but it's [our] first defeat in LaLiga; we won nine in a row, and that also has to be taken into account.

"Now it's important to analyse and react."
