AFRICA AND ASIA ARE ALTERNATIVE OPTIONS
Africa, I feel at least, is the third strongest footballing continent after Europe and South America. This is not in terms of domestic league structures, but participation, and the number of great players produced by the continent. Weah, Essien, Eto'o, Drogba, Kanu, Lauren, the Toure brothers, etc. all stand amongst the very best in their positions and were from Africa. There has not been a top team in club football over the past twenty years or more that has not had a top African player in it. Real Madrid, Barca, to Juve, Bayern, PSG, Arsenal, Chelsea, Liverpool, Man United, and Man City, can all lay claim to at least one.
And whilst still a very poor continent economically, Rwanda is the official sleeve sponsor of Arsenal, which stands as a record for any club on Earth. Football is huge in Africa, and with Morocco literally, just over the water from Spain, this is a prime opportunity for La Liga.
Asia is mixed, as whilst the sport is strongest perhaps in the Middle East and East Asia, southern and central Asia still lag behind. Cricket and localised sports such as Kabaddi, still predominate in India, Pakistan, Sri Lanka, and Bangladesh.
Nonetheless, football has a huge and passionate following in a number of Asian countries, and it's something that can be readily exploited.
Big English clubs such as Arsenal and Chelsea have gone on tours to Hong Kong, Singapore, and Australia, which met with great enthusiasm and fanfare from the local supporters. There is no reason why the Spanish clubs cannot do the same.
