Liverpool boss Klopp forked out £44million to sign Fabinho from Monaco back in the summer, beating Manchester United and PSG to secure the player’s signature.
Initially, however, the Brazil international’s Reds career struggled for lift-off with Klopp regularly leaving the midfielder out.
Fabinho had to wait until October to make his first start for Liverpool but now, six months on, the Samba star is a key part of Klopp’s midfield.
And the 25-year-old has now admitted that he was frustrated by his manager’s reluctance to throw him into the mix.
“Pre-season went great for me,” he told the Daily Telegraph.
“I was playing every game but when it came to the start of the season the coach had everyone available and he wanted to go with players who he had already worked with before.
“It was a case of learning, watching and getting up to speed. Watching from the side-lines as to how the team works.
“I was hoping for opportunities early on but I knew this could happen, I knew that I needed to be patient, work hard and that when the chance came to play I had already adapted and I could see what the team was trying to do so I was up to the pace of it.
“I needed time physically to improve. The intensity of it.
“Being in midfield, in general, you don’t have a lot of time to think and in the Premier League that’s even less of the case.
“You just don’t have time to think. And in the first few games I think I played well but I needed to be faster.
“Jurgen Klopp wanted me to learn how to play in the team and what my role was and I think time was the most important thing in doing this.”
Fabinho also admitted he feels Liverpool deserve something out of the season.
The Reds are in contention for the Premier League title – sitting two points behind Manchester City – and are on the brink of reaching the Champions League semis.
And Fabinho added: “Right now this is the time of the season when everything is being decided.
“It’s been a great season and it would be a shame if we didn’t end it with a title after all the effort we have put in.
“We have five games left in the league and hopefully four in the Champions League.
“The team is in a good spot.”
