Javier Mascherano believes the manner in which the Camp Nou outfit were swept aside last night is 'worrying'.
As per Sky Sports, the former Liverpool player said: "The opposition not only beat us, they also outplayed us, which is worrying.
"It always hurts when we lose. This is nothing new to us, we're seasoned veterans. The best thing to do is turn the page, focus on Saturday's game and putting in a good performance."
The defeat saw the defending champions surrender their early lead over both Madrid clubs and they now sit fifth in Liga BBVA, a point behind Real Madrid, Celta and Villarreal.
They have an instant opportunity to respond with newly promoted Las Palmas travelling to the Camp Nou on Saturday.
