Klopp told Moreno he was going to sign a new left-back this summer which he duly did – Andy Robertson.
But the Spaniard wasn’t happy with the way it was conducted.
He says the manner in which it was done was “wrong” – then labelled his relationship with Klopp as “strange”.
Moreno told Spanish newspaper Marca: “My idea was to stay, work hard and earn my place.
“Klopp told me he was going to sign a left-back and that he couldn’t promise me game time.
“I thought this was wrong, I spoke to my agent but he told me just to keep working.
“There came a point where I trained, looked around and knew that no matter what I did, they were not going to play me.
“Seeing my daughter every day and being with her saved me. It allowed me to isolate myself from what was happening.”
Asked about his relationship with Klopp, Moreno continued: “It has been strange. He arrived and I played every game, then at the start of the next season I disappeared.
“When I saw James Milner, a right footed midfielder, at left-back I knew something was happening. He did not give me any explanations.”
Moreno has since gone on to be Liverpool’s No 1 left-back and he has been called up to the Spain national squad for the first time since 2014.
On what it’s like now between himself and Klopp, Moreno added: “It is a totally different relationship. He even speaks to me in Spanish sometimes.
“He’s helping me a lot and I think it shows. I’m a more mature player with better defensive awareness.”
