Barcelona great Luis Suarez slammed Osasuna after Sunday's thrashing.
Barca were comfortable 4-0 winners on the day, though Suarez insists nothing can be read into the performance.
He explained: "It is a game in which no conclusions can be drawn.
"Osasuna has not put anything into the match to win. I don't know what the f.. they've played. It was a joke."
Luisito also said: "Barça found too much room from the first minute by Osasuna. They have known how to take advantage of the rival's weaknesses in a game that only lasted half an hour. Osasuna was a very weak rival. I hope that on Thursday they (Barca) play better than the previous match against Galatasaray."
