The Uruguayan forward was frustrated with decisions going against him during Liverpool's 1-1 draw with Norwich.
"He needs protection and I don't think he got that out there," said Dalglish. "His integrity has been called into question and I think maybe he is suffering from that at the moment."
"It is their integrity that needs questioning not his. On the football pitch he is exemplary, a fantastic footballer and we have 100% faith in Luis and the way he conducts himself."
