Liverpool boss Jurgen Klopp won't put any limits on Naby Keita.

Keita, a £52.75m summer signing from RB Leipzig, followed an encouraging pre-season with a hugely impressive display on his competitive debut in last Sunday's 4-0 Premier League opening day win at home to West Ham United.

“Naby, we all have no clue how good he can be," admitted Klopp. “He's too young to judge him. What can we say?

“Obviously he learned very quickly already in the last few years, from Austria to Leipzig, now here.

“So he adapts constantly and brings himself to the next level. Adapts to the other players, uses them really well.

“I don't want to make it too big (a thing), it's just that I don't know. If you asked me what his greatest strength was, I couldn't say it really. It's not because he's not long enough here.

“But he's a very smart footballer."
