Liverpool striker Roberto Firmino admits manager Jurgen Klopp has been "sad and angry" this season.

Speaking with ESPN Brasil, Firmino discussed how Klopp has been reacting to the Reds' inconsistency this season.

The No.9 said: "He gets sad, he gets angry. Nobody likes to lose, especially him. Our team got used to winning. But, in this difficult time, we have to analyse our negative points and turn them into positive ones. We have to look to always give our best to each game.

“We had an excellent game against Arsenal. We didn't concede goals, we were solid in defence, we scored three goals and we won.

"Three days later, we lost a very important game for the Champions League. We know that we still have the second game, that there's nothing won or lost yet. We can reverse the score and come out winners.

"But we know that, especially in the first half against Real Madrid, we were very bad. Fortunately, we managed to score a goal and we have a chance to reverse that."
