Mourinho said: “There were definitely mistakes with people not adapting to their positions.
“I was waiting for 15 or 20 minutes to go by with no goals conceded and the confidence arriving. But when the team is very fragile on the pitch and mentally not so self confident it is difficult.
“In the second half I think we played better but Liverpool defended well and were full of confidence. They knew they could be adventurous because our defensive line is fragile.”
