Hugo Sanchez fears the consequences that Lionel Messi's Barcelona exit will have on LaLiga Santander.
The Argentine has asked to leave the Camp Nou this summer and is now locked in an internal conflict with the club.
"Javier Tebas is very respected in Spain as he's making teams very rich because of the amount of money he is receiving from the selling of TV rights across the world," Sanchez told Futbol Picante.
"Tebas usually sells his product and makes four-year and five-year contracts.
"The departures of Neymar and Cristiano [Ronaldo] affected him a lot.
"The exodus of talent from Spanish football obviously makes it less attractive.
"Messi leaving is going to be a tremendous blow.
"Even though [Tebas] says that LaLiga will be the same without Messi... no.
"I'd like it if, when the four-year contracts are over, when they know that Messi, Neymar or Cristiano are not there, they're going to have a great fall.
"The English league is going be the most watched if Messi arrives."
