Luis Enrique compared the poor performance of his Barcelona side in their 3-0 loss at Juventus to the team's defeat against Paris Saint-Germain in the first leg of the previous round.
Paulo Dybala struck two brilliant goals and Giorgio Chiellini headed a third goal to put the Serie A leaders in full control on a stunning night in Turin.
Barcelona had to overturn an even greater deficit against PSG, coming from 4-0 down after the first fixture with an incredible 6-1 victory at Camp Nou in the second leg, but Luis Enrique believes it will be hard for his team to repeat the trick.
"It was a difficult first half, very similar to the one in Paris, and the second was much better," Luis Enrique told Mediaset Premium.

Luis Enrique refused to lay the blame for Barca's loss at the feet of his players, insisting they had not been prepared well enough to face Juve, who are unbeaten in 22 home matches in European competitions.
"A coach does everything to help the team and prepare them, but evidently I did not," he said.

"We have to improve, learn from these mistakes, analyse the game carefully and realise where we went wrong.
"It's not good to pick on single players after a defeat. It's a defeat for the whole team, starting from myself."
