Salah has scored 12 goals in 17 games for the Reds since arriving from Roma this summer, but Klopp still wants more from his star man.
He said: 'He could have scored even more. He's a fantastic player and can still improve.
'Very often he is in decisive areas and that makes him such a threat.'
The Egyptian will be hoping to continue his fine form when Liverpool face Southampton at Anfield on Saturday afternoon.
