LONDON — In European soccer’s relentless search for growth and new revenues, Spain’s La Liga has been among the most aggressive of the continent’s top leagues.

Under a plan hatched and pressed by its chief executive, Javier Tebas, La Liga has planted its flag across the globe, opening offices in far-flung cities — not just obvious markets like New York and China, but also in Belgium and Singapore and South Africa, among others — in a bid to scoop up new fans and television and sponsorship dollars.

Tebas has even gone to court in the United States in an effort to hold a league game outside Spain. But there is one red line Tebas said that he is unwilling to cross: La Liga and its teams should not, he argued, be playing matches in Saudi Arabia.

To Tebas, the kingdom, despite its high-profile campaign to rebrand itself as a modern and tolerant society led by a youthful crown prince, should not be permitted to use international sporting events to mask its record of human rights abuses.
