Barca manager Luis has likened his team's four-goal defeat to Paris Saint-Germain in the UEFA Champions League last-16 first leg clash in Paris to the 3-0 loss at Juventus in Tuesday's quarter finals first leg tie in Italy.Barcelona were left needing another ‘remontada’ as Paulo Dybala’s brace fired Juventus to a 3-0 victory in Tuesday’s Champions League quarter-final first leg. Juventus 3-0 Barcelona Match ReportIt was something of a case of deja vu for the Enrique and Barca who now need four unreplied goals to go through to the next round as they crashed to yet another seemingly disastrous first leg defeat."It does not matter if I think the result is fair or not, it is what it is. It felt like the third half of PSG vs. Barcelona. It is very serious and sad, we were impotent in the first-half, it was a very tough game." the Barca boss said on MarcaOn whether he felt that the defeat in Turin was worse than the previous setback in Paris, Luis Enrique admitted his current state to be more negative than back at Parc des Princes."We have revived a nightmare. "We have to determine why we've been so bad. This one has cost me more [than the PSG game]."Our positioning and some more details on the pitch were below the level required, and the intensity must be much higher," Luis Enrique lamented. "In the Champions League, against an opponent like Juve, you can not do that." The reigning Serie A champions put on a masterclass of football from back to front and a first-half brace from Paulo Dybala and a second-half header from Giorgio Chiellini have the Italians poised to clinch a semi-final berth when the two teams meet in the return leg on April 19.
