Villarreal suffered their first defeat since returning to the Spanish top-flight on Sunday as Nosa Igiebor’s first-half goal handed Real Betis a 1-0 win.
The Nigerian midfielder pounced nine minutes before half-time to steer the ball home after Villarreal keeper Sergio Asenjo had parried Joan Verdu’s effort.
Villarreal pressed for an equaliser after the break, but it was Betis who looked more likely to score again on the counter-attack and Asenjo did brilliantly to deny Verdu when he was played clean through on goal by Jorge Molina seven minutes from time.
The visitors’ miserable evening was rounded off when coach Marcelino Garcia Toral was sent to the stands in stoppage time for dissent after the referee only gave a corner when Villarreal thought Javier Aquino had been fouled inside the area.
Earlier, Elche secured their first win in the top-flight for 25 years as they won 1-0 away at Celta Vigo.
