Tebas has questioned Neymar’s behaviour.
LaLiga president Javier Tebas is hoping Barcelona do not sign Neymar because of the Brazilian’s attitude.
The 27-year-old has been heavily linked with a return to the Camp Nou, two years after a world-record €222million switch to Ligue 1 champions Paris Saint-Germain.
And this comes after PSG president Nasser Al-Khelaifi said last month that they will not tolerate any "celebrity behaviour" at the Parc des Princes.
"I prefer that Neymar does not return to Barca," he told Onda Cero.
"We always want to bring great players, but in the case of Neymar that behaviour is not good for the competition because in the end the news is if the player has done this or that.
"We have worked a lot in LaLiga to maintain the values and we don't want to change the image."
