Barcelona manager Luis Enrique believes his team's Champions League exertions played a part in their 2-1 La Liga defeat to Deportivo La Coruna on Sunday.
The Catalan giants beat PSG 6-1 on a historic night in European football last Wednesdaybut found it tough going away at the Estadio Riazor, with goals from Joselu andAlex Bergantinos cancelling out Luis Suarez's earlier equaliser.
"Only someone who has lived what we lived this week can understand what it means, but professionals need to know how to cope with these situations,"Enrique said, as quoted bySky Sports.
"We knew it would be difficult here but what happens before a game always has an impact in the next. It's better to arrive at a game feeling euphoric than pessimistic, we were focused, but westill lost."
Barcelona had put together a good run of form in recent weeks, closing the gap on league leaders Real Madrid. However, Real capitalised on Barcelona's slip later on Sunday by beating Real Betis 2-1, and Enrique said he was disappointed with his side's inability to continue their recent momentum.
"We lacked clarity in the final few metres and it's a shame because this game was crucial to keep our confidence high and for our rivals to see that we mean business," he added.
"We didn't have the fluidity we needed to overcome their deep defending. They grew in confidence and we made errors. Today it was crucial that we scored first but they did. We have to accept this defeat and remember there's a lot of games left."
