Lionel Messi rarely appears before the media, but he did not prevent himself from analyzing the causes of Barcelona's disastrous season after a 2-1 loss to his guest, Osasuna, in the Primera Liga on Thursday.

Messi described the team as "weak" and "inconsistent" and "very easy to score in front of it", and the team leader called for immediate changes after losing the league title to Real Madrid, stressing that it is not good to use the massive rally of the rival as a justification for the loss.

"Moundo is exploding," wrote Mundo Deportivo.

Barcelona - which was once a team of football, show and skills and the school "Tiki Taka" - now looks to the Champions League, which has not won its title since 2015 despite its dominance in Spain most of the time.

However, few may bet on winning the mini-championship in Lisbon in August, and even Messi does not place high hopes on the Napoli pass in the second leg of the final in the Camp Nou on the 8th of next month after the 1-1 draw back.

"I said a while ago that it would be very difficult to win the Champions League if the team continued to play like this and it was not good enough to win the league," the Argentine star said.

"If we want to win the Champions League, we need a lot of changes, otherwise we will lose to Naples also ... We need to clear our mind and this pause should give us an opportunity to think about the very bad things that have occurred since January until now."

Sittin's future

Messi's words carried a scathing attack on the term of coach Kiki Sittin, who took over in January after Ernesto Valverde was sacked while Barcelona were top of the league with a goal difference.

Sittin was not trusted and admitted that he was not sure whether the club would renew confidence in the Champions League.

"I hope to stay, but I don't know ... I agree with Messi on some things that we need to think deeply," he said.

Club president Josep Bartomeo said that Sittin will continue with the team in the next season, but he does not guarantee that he or the coach will stay for a long time as Bartomeo's term ends in 2021 and he was prevented from voting for a new period.

Victor Fonte is running for election and has vowed to take over as legend Xavi Hernandez as coach.

The former midfielder and the current Qatari Al Sadd coach have acknowledged that he and his crew are already preparing for Barcelona.
