Paris Saint-Germain have been disrespectful by publicly announcing their interest in Lionel Messi, according to FC Barcelona presidential candidate Joan Laporta.

The Argentine is the final six months of his contract at the Camp Nou, which allows him to open talks with foreign clubs over a possible transfer next season.
PSG sporting director Leonardo recently revealed that the Ligue 1 club is considering a possible deal for the six-time Ballon d'Or winner, although those comments did not sit well with Laporta.
"The club must be capable of making a good proposal that Messi is willing to accept. That depends on the club," he said at a press conference, according to Goal.
"I would understand any answer (from Messi), but he needs to know what the proposal is; that requires urgency. It is getting more complicated all the time to make a convincing proposal. He's free to negotiate with other clubs now and Barca are still without a president.
"It is disrespectful to Barca that clubs like PSG publicly say they are going to sign Messi. This coming from a club-state that have bypassed the rules. We cannot allow clubs and states the luxury of destabilising another club.
"In that sense, we will have to speak with UEFA and FIFA to avoid such actions. PSG must abstain from (talking about Messi). It is out of place for another club to speak about him. And, at the moment, there is no president in place to respond to this lack of respect."
