The Guinea international arrived in the summer, 12 months after the Reds paid £53 million to buy him RB Leipzig, and the nature of his game was such he was tipped to make a huge impact.
However, after a promising start in his first couple of matches the 23-year-old has struggled for form, not helped having to learn a new language and culture, an injury which sidelined him for a month in October and being asked to perform a slightly different role from the one he had in the Bundesliga.
He showed flashes of his talent in Wednesday’s 1-1 draw with Leicester, only his 10th start in a total of 17 Premier League appearances, and Klopp is prepared to be patient with the third-most expensive player in the club’s history.
“Yeah, happy so far but still a lot to come,” said Klopp ahead of Monday’s trip to West Ham.
“Naby is an outstanding player but he still has to improve; minutes, games, language, all that stuff.
“Everything will be fine, and it is fine so far, but we can really expect a lot more still, that’s how it is.”
Manuel Pellegrini’s West Ham are on a three-match losing streak, as Leicester were in midweek, but despite the Hammers being rolled over 4-0 by Klopp’s side on the opening day of the season, the Reds boss is taking nothing for granted.
“They had a really bad start, I think they had maybe only two points after six match days, but since then they are nearly a top-six side. That’s what we should expect.
“(They have the) most experienced manager in the Premier League at the moment, really good football team, good signings in defence, experience in the full-back positions.
“(Declan) Rice, fantastic development next to (Mark) Noble in midfield, experience and youth. Then you have the wings, really strong, (Felipe) Anderson fantastic signing, and Marko Arnautovic an outstanding striker.
“(Samir) Nasri is now around, (Robert) Snodgrass is back on track, Lukasz Fabianski in goal, it’s a really good football team. That’s what we have to be ready for again.
“We can’t compare with the first game of the season. We expected a difficult game that day but it was not so difficult for two reasons: we were really good and they were not ready.
“Now they are ready and it’s a completely different cup of tea.”
