Now the 23-year-old wants to call on the self-confidence and spirit of former Sweden striker Zlatan Ibrahimovic.
This is how I am, this is my habit," said the Hungary international, per the Liverpool Echo.
"To some, I still seem arrogant. I don't call it arrogance, but self-confidence, as Ibrahimovic once said. You need self-confidence to be able to maintain this level, it is not so simple in everyday life."
Of course, I always knew about LFC, that it was a huge club, even before Klopp, and when he arrived Liverpool became even bigger," he added.
"He's been here nine years, I was 14 then, so I only see the time since he's been here. I am very attracted to this place, the team, the people, the players the goals, everything.
"However, there are things that you cannot claim as your own from the first day. You go into the dressing room, and of course they welcome you, but then who do you turn to, who do you talk to? Who do you go to breakfast with, who do you go to the gym with? There are a few there, but they probably don't talk to me because they don't know what the common topic is. This takes time, learning to get to know the other. That was the hard part."
Of Jurgen Klopp, the midfielder added: "I think he's the best coach I've ever worked with, extra as a human being, extra in football knowledge, extra in his attitude towards players, extra in his attitude towards the team."
