Atletico Madrid open their campaign against Malaga the following Wednesday, before Real Madrid and Barcelona finally get going on the second weekend. And, with LaLiga receiving an extra Champions League place, Real Betis also claimed a spot at Europe's top table. Here, calling on the 10,000 data-led simulations run by the Opta supercomputer, we forecast how the 2026-27 LaLiga season might play out. Valencia, under Rafael Benitez in 2003-04, were the last team other than Barca, Madrid or Atletico to win LaLiga, and the supercomputer does not foresee a surprise champion. Below Barca and Madrid, LaLiga has been one of Europe's most fiercely contested leagues in recent years.
