The real problem with Liverpool has been pointed out by Klopp, who watched as his side played put a 1-1 draw against 10-man Rubin Kazan in the Europa at the Anfield.
Liverpool went behind in the 15th minute and it took the reduction of the Russian team, before the English club could equalize via Emre Can.
Liverpool had 35 shots, but despite playing for the majority of the game against a 10-man side, they couldn’t find the much needed winner.
“The team is not full of self-confidence, they lost their grip on the game,” Klopp told BT Sport.
“They sat deep and we had to find solutions. Sometimes we found them. We had many shots on goal. I would say 98 per cent is okay, the last two per cent â€“ the decision-making per cent â€“ was not on the pitch.
“The guys tried what they did and we got this very nice goal, but of course we could defend better.”
Klopp’s men are four points behind group leaders Sion, who beat Bordeaux 1-0 to leave Liverpool second, only one point ahead of the Ligue 1 side and Thursday’s opponents.
