Keita has made four appearances for the Reds so far, starting in the wins over West Ham United, Crystal Palace and Brighton and Hove Albion before a substitute outing when victory was secured at Leicester City before the international break.
"I think it's fair to say that the Premier League is a tough league," said Keita in the new edition of the official Liverpool FC magazine.
“I'm very motivated to be playing in it – it's an attractive proposition – but I've been told by many people that a lot of overseas players come into the Premier League and they take time to integrate, depending on the circumstances.
“So playing in the Premier League can be difficult, but I am very motivated to play here, not just for myself and my teammates, but for the club.
“Everybody around me has been very supportive towards me so I am certainly giving everything I can to get settled into the team quickly."
Keita admits he's eager to hit the goals trail.
“First and foremost, I should say that I'm very much a team player and I always think about the team first," he said.
“The Premier League is different to other leagues where I have played and everybody knows it is very tough, but I will do my best to beat my own personal records.
“I'm the kind of person who thinks that if I score eight goals in one season my objective must be to score nine goals in the following season. That's the kind of mentality I have."
