The Portugal international joined the Reds in September from Wolves for an initial fee of £41million, although that fee could end up rising to £45million.
“With the season underway already, it was up to me to find a way to get into the team and not the opposite. That's what I did with the help of Jurgen [Klopp].
“He's a fantastic manager who took care of me. When I first arrived, he had a meeting with me and he explained how the team works.
"Then it's down to the player to try to learn as fast as you can and to prove to the manager that you can be an important player for him on the field.
"He sent me a text message as soon as I knew I was signing for Liverpool and he has helped me.
“The Brazilian players speak the same language so people like Fabinho, Roberto Firmino and Ali (Alisson) have helped a lot too."
