Pennant left Anfield on a free transfer to join Real Zaragoza in the summer after three seasons with the Reds.
He recently blasted Kuyt - who took Pennant's place in Benitez's side - labelling the Dutchman as a failed forward who was accommodated in the team because of his high transfer fee.
While Reds boss Rafa Benitez has since leapt to Kuyt's defence, the Dutchman himself refuses to get into a war of words.
Nothing badHe told the News of the World: "I have nothing bad to say about him.
"It's up to Jermaine what he says but I always enjoyed having him as a team-mate so I was surprised by what he said."
Liverpool take on Chelsea at Stamford Bridge on Sunday and Kuyt insists he will be fully focused on the job in hand.
He said: "When I step on the pitch I don't think about anything except winning the game and enjoying myself as much as possible.
Push harder"We've done well, played some unbelievable games and gone really close, but we know we have to do more and push even harder.
"We've consistently shown we can beat the best teams in the Premier League, especially last season. Now we have to show it again."
