Dalglish praised Jones, who as third-choice goalkeeper is now in line to play in Saturday's FA Cup semi-final, and matchwinner Andy Carroll for their contributions.
"I think Brad had a bit of a psychological advantage because the two (he and Yakubu) had been at Middlesbrough together," he said.
"It was a great first contribution in the Premier League to save a penalty, I am sure he will remember that.
"I think Andy is very confident and got what he deserved. He worked really hard and scored a fantastic header - I don't think confidence is a problem."
