Ronald Koeman is critical of his players, after FC Barcelona on Saturday visiting Cádiz CF (2-1) suffered their fourth defeat this season in La Liga.

The Dutch trainer is disappointed by the volatility of the Catalan club.

"It is unbelievable that we lose on such a goal," said Koeman of Cádiz's 2-1 in the 66th minute in Estadio Ramón de Carranza.

After a bad throw by Jordi Alba, Clément Lenglet made a mistake and keeper Marc-André ter Stegen did not intervene properly, which meant Álvaro Negredo was accurate.

"That was a mistake that you don't expect this team to make," Koeman continues.

"It shows that we were not focused. The attitude of the players was not good."

According to Koeman, it didn't just go wrong with Cádiz's second goal.

"In general we were not focused. Our attitude on the ball was not good. Everyone has to think about what went wrong and what needs to be improved."

'This is another step backwards'

Barcelona is seventh in La Liga after the defeat in Cádiz.

The gap on leader Atlético Madrid is twelve points, although the Madrid people have played one more match.

The contrast is great with the Champions League in which Koeman's team is still without losing points after five group duels.

"The inconsistency has to go," says Koeman.

"And our attitude must improve, otherwise we will remain behind in the competition. This defeat is another step back."

Barcelona is already waiting for the next match next Tuesday.

Juventus will then be the opponent in Camp Nou in the last group match in the Champions League.

Five days later, a home game against Levante in La Liga awaits.
