BUENOS AIRES, Nov 26 — With eight trophies up for grabs from next year, a first division counting 30 teams and formats that can change seemingly on a whim, the Argentine league is at risk of alienating supporters in the home of the reigning World Cup winners.

Already somewhat of a rarity to outsiders with its two-stage season — each half lasts six months and they are known as the Apertura and Clausura (opening and closing) championships, respectively — the league has recently become even more singular.
