Benitez is sure Dalglish will be given time to improve the club's league position as he has the support of owner John W Henry.
Benitez said: "They have to carry on, keep going.
"He has the support of the owners and that is key if they want to do things in the future.
"They are spending big money and doing well and they have won the Carling Cup. For me I have to respect the job Kenny is doing.
"I will not criticise him and I wish him all the best."
