The 29 year-old joined the Merseyside club on a free transfer last summer.
"Joe Cole's been fantastic since he came here, his application and
dedication on the training pitch has been superb," Dalglish told
reporters at a press conference at the club.
"Joe's attitude has been brilliant and anything he gets, he fully
deserves."
"Has he got the desire? I think you are insulting the boy there," he
said.
"When you ask if someone has desire, I think you are insulting them.
"It's up to you, I've just waxed lyrical about his dedication, his
application, if you want to get into a confrontation with Joe, fine, that's
up to you."
