"Last week (against Sunderland) maybe I was being a wee bit romantic with Luis," the Scot said.
"It was unfair on him, he was coming back and was on such a high and looked sharp in training. I thought I would give him a game.
"Maybe last week it was the wrong decision from me.
"He still scored the goal, still played well, but he just never had the energy he normally has. Maybe we just brought him back a wee bit too soon."
Dalglish added: "We have got to manage Luis' circumstances the same as we have everybody else's. There were another four or five lads there who we had for the first time.
"Raul Meireles has had a difficult pre-season with injuries so we have got to look after him as well as Luis."
