LaLiga president Javier Tebas has warned FC Barcelona he will not turn a blind eye to the league's fair play rule in order for the club to register Lionel Messi.
The Catalan giants need to reduce their wage bill if they want to register their four new signings and Messi, who is yet the reported five-year deal on the table.
"No, I won't [turn a blind eye] for Messi, it's impossible. There are many workers [at LaLiga] and in the economic control [department] as well," Tebas said on Radio MARCA.
"This is a right that the clubs have and we have to safeguard the integrity of LaLiga.
"We often have to explain [the economic controls] to agents and players because they don't know about it or think clubs are deceiving them, and we've had to explain it in recent years."
Tebas also admitted his surprise that the six-time Ballon d'Or is yet to receive an offer from Manchester City or Paris Saint-Germain, who were heavily linked with the player.
"We'll have to analyse everything properly, because if there are dismissals for economic reasons but then they bring in Messi and others... we'd have to look into that," said Tebas.
"Right now I can only give my opinion, and that is that it is odd that there has been no offer [for Messi] from Manchester City or Paris Saint-Germain.
"And I firmly believe there isn't and that the player wants to stay."
