Real Betis came from behind to beat Porto 3-2 in a thrilling Champions League match at Estadio La Cartuja in Seville on Thursday.
Isco scored the winning goal from the penalty spot in the 84th minute as the Spanish side secured their second straight victory in the competition.
Abde Ezzalzouli gave Betis the lead early in the second half, but Porto responded with goals from Gabri Veiga and Samu Aghehowa.
However, Cucho Hernandez brought the hosts level before Isco completed the comeback. Betis created several chances in the first half but failed to find the net.
Porto thought they had taken the lead when Martim Fernandes scored from close range. However, VAR ruled out the goal after spotting a handball by Borja Sainz during the build-up.
The first half ended goalless, but the match changed quickly after the break. Ezzalzouli opened the scoring in the 47th minute with a brilliant curling shot from outside the penalty area.
Antony almost doubled the lead two minutes later, but his effort struck the post.
Porto punished that miss in the 54th minute when Veiga scored with a fine free kick from around 25 yards. The visitors then took the lead in the 61st minute.
Pepe set up Aghehowa with a clever backheel, and the striker fired a powerful shot into the net off the underside of the crossbar.
Betis responded by making changes in attack. Hernandez came on for Troy Parrott and made an immediate impact. He scored the equaliser in the 74th minute after Antony found him with a pass from the left.
The hosts continued to push for a winner and received a penalty in the closing stages. VAR spotted a foul on Angel Ortiz inside the box, and the referee awarded Betis a spot kick.
Captain Isco stepped up and calmly placed his shot into the bottom corner in the 84th minute. Porto failed to find another equaliser as Betis held on for an important victory.
The result gave Betis six points from their opening two Champions League matches. It was also their first home victory in the competition since beating Chelsea in November 2005.
