Pau Cubarsi was at a loss to explain Barcelona's defeat to Atletico Madrid on Saturday night in La Liga.
The hosts dominated the game but ended up on the losing side after missing a hatful of chances.
Cubarsi spoke to the media after the game and admitted it's a tough result to take.
"It's inexplicable. It's our fault. We had the game in our hands. We wasted it. We're screwed but we have to rest and focus on 2025, to start with everything," he told the media.
"We played a great game. You see the chances, the position of the ball... the final point up front let us down a bit. It's normal. We have to focus more on that.
"We wanted to come out with everything we had from the start. We had some bad results. We had a very good game but we missed two silly details that marked the game for us.
"Our level of play is good, we lack finesse up front. The break will be good for us to relax and come back with desire."
Barcelona have a lot to think about over the festive break and don't play again in La Liga until January 18 due to Copa del Rey and Spanish Super Cup fixtures.
