FC Barcelona captain Lionel Messi was very critical of the club's performances this season after losing out on the LaLiga title to Real Madrid.
The Catalan giants were top of the table when the season resumed last month, but they had to watch their fiercest rivals lift the Spanish league title on Thursday evening with a game to spare.
The Argentine forward did not hold back after the shock loss to Osasuna last night and sent a warning to his teammates ahead of their UEFA Champions League tie against Napoli next month.
"We didn't want to end the season like this but it represents how the season has gone," Messi told Movistar +, as per Metro.
"We were a very erratic, very weak, low-intensity team… We lost a lot of points and today's game is a summary of the season.

"We have to be self-critical. Starting with the players but doing a global self-criticism. We are Barca and we have to win everything.
"We can't look at Madrid…Madrid have done their job, but we have helped them a lot.
"If we want to win the Champions League, we have to change a lot. If we continue like this, we will lose the game against Napoli."
