Jurgen Klopp has hailed Naby Keita's "outstanding" potential as he revealed the one key aspect the Liverpool new boy can improve.
Keita, a £52.75million summer arrival from RB Leipzig, enjoyed another encouraging display in the 2-0 Premier League win at Crystal Palace on Monday night.
The Guinea international wowed the crowd with one turn to lose Andros Townsend before creating a chance for Mohamed Salah, while his overall performance earned plaudits.
Klopp spoke over the weekend of having no idea just how good the 23-year-old can become.
And with Keita having played only two competitive games for his new club, Klopp believes there will be plenty more from the player over the coming weeks and months.
Naby Keita of Liverpool in action
"He's very shy and not very extroverted but on the pitch you don't see it," the Reds boss told Sky Sports.
"He needs to settle a little bit. He's next to Sadio (Mane) all the time (in training).
"Everybody loves Naby but I don't know if he loves us because he doesn't speak a lot. But football-wise you can see the potential is outstanding but we have to give him time.
"Defensively he's very stable in his challenges. Tactically he can improve, and he must improve, but what else I don't know."
