Dalglish was also delighted by Liverpool captain Steven Gerrard’s comeback for the club. The match between Liverpool and United ended in a 1-1 draw.
He said: “I thought he was everything he’s been for the club, and it was fitting he got the goal.”
Dalglish added: “The fact we have Steven Gerrard playing is a real boost to us. It is fantastic for him he has crowned his first start for a while by scoring.
“He has made a fantastic contribution to this football club and he will continue to do that.
“To see him back was brilliant for us, but more importantly really encouraging for him. He still has a bit to go, but it was fantastic to see him starting a game and he deserves that reward of a goal.”
Dalglish continued: “I thought in the first half the two teams almost cancelled each other out, and the second half started much the same.
“We scored the goal then they equalised, then their keeper made two or three good saves. I thought the boy (De Gea) was struggling?
“He wasn’t struggling today, he made two or three great saves.”
