The Brazilian has made a positive impression since his January move from Inter Milan.
"Things have gone really well for me here so far," Coutinho told the Liverpool Echo.
"Maybe because I played in Italy and spent six months in Spain last season that has helped me adapt more quickly to English football.
"Also I must thank my team-mates as they have helped me a lot with my first few games. Everyone has made me feel so welcome. The games are quicker and more physical but I like that. I am learning all the time.
"Every player wants to improve and get better and I am the same. I am still young and have so much still to learn."
