Barcelona coach Pep Guardiola doesn't share club president Sandro Rosell's vision of a Spanish league with only 16 teams.
Guardiola said to drop four teams "isn't a bad idea" but "all the top leagues have 20 teams."
The Catalan coach said Rosell "has his motives" for suggesting the move, but doesn't expect it to happen since "many cities deserve to be in the first division."
Barcelona look to extend their unbeaten start to 16 games on Wednesday in a Copa del Rey first-leg match at third-division Hospitalet, where the Spanish champions will play on an artificial surface.
Guardiola is likely to use mostly youth team players, with Lionel Messi, Javier Mascherano and Daniel Alves away on international duty.
