The Argentine superstar gave a frank assessment of the Blaugrana’s domestic campaign after seeing Real Madrid win the top-flight crown   Lionel Messi has blasted Barcelona’s performance in 2019-20, insisting “if we continue like this, we’ll lose to Napoli” in the Champions League.

Barca suffered their sixth La Liga defeat of the season on Thursday night, while Real Madrid picked up the win they needed to secure their first La Liga title since 2017.

Quique Setien’s men were humbled by Osasuna 2-1 at Camp Nou, with goals from Jose Arnaiz and Roberto Torres cancelling out a trademark Messi free-kick.

The result leaves the Blaugrana seven points behind Madrid, who beat Villarreal 2-1 at Santiago Bernabeu to increase their advantage at the summit heading into the final round of fixtures.

Messi aired his frustration in a post-match interview with Movistar +, expressing his belief that Barca made it far easy for their arch-rivals to dethrone them.

The six-time Ballon d’Or winner also raised doubts over the team’s chances of winning their last 16 Champions League second leg tie against Napoli next month, which will be played in Lisbon with the aggregate score currently locked at 1-1.

“We didn’t want to end the season like this but it represents how the season has gone,” Messi began.

“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.”
