Rooney looks to be re-charged under David Moyes at Old Trafford.
Dalglish wrote in the Mirror: "I think there are great similarities between Luis and Wayne Rooney. Their characters are the same.
"The most important thing, the quality that reassures the clubs they play for and the fans that support them, is that they will always give everything on the pitch.
"Whatever their problems off the pitch, they will never let their team-mates down on it."
