Defending Copa del Rey Champions Real Betis opened their defence of the title with a 4-1 come-from-behind win over CD Ibiza.

The match had to be played on a practice pitch in the Balearic Islands as Ibiza could not reach an agreement with local officials to host it at the bigger Can Misses stadium.

A practice pitch being used for a domestic match seemed to be the only surprise of the day until the 26th minute when José Miguel Bernal Ortiz unexpectedly put Ibiza ahead.

Their chances of a miraculous win lasted until the 54th minute when Willian José equalised the tie and opened the floodgates for his side. Edgar González gave Real Betis the lead after just 4 minutes before Nabil Fekir and an own goal by Iker Murua wrapped up the scoreline in front of fewer than 2,000 fans against the 4th tired Ibiza side.

Betis, who won their fifth Copa del Rey title last year, was among the four teams entering the competition in this round because they are playing in the Spanish Super Cup that begins next week, along with Valencia, Real Madrid and Barcelona with all sides progressing.

In other results Athletic Bilbaoeased past third-division club Eldense 6-1, with Nico Williams, Alejandro Berenguer and Iker Muniain among the scorers while Osasuna needed extra time to defeat third-division opponent Gimnastic 2-1 after a 1-1 draw in regulation time.
