The incident occurred in the 85th minute with Barca up 2-0. Cadiz later confirmed that the spectactor had stabilized and been taken to hospital but the incident was a scary moment and the pause highly unusual.
Home goalkeeper Jeremias Ledesma had raced to the sidelines to get a defibrillator which he handed to paramedics who were treating the fan. Several players were seen praying.
“It was an eventful situation,” Xavi told Movistar. “Some said a supporter had fallen from the stands, others that it was a heart attack.
“If there had been a misfortune of any sort, we would have stopped the game. We are talking about a human life and that is above football.
“Luckily no misfortune has happened and we have been able to play football.
“In the end it was a matter of humanity, with human qualities coming out. Between all of us, we have tried to add and we hope it will turn out well for the person involved.”
Meanwhile, the win is another boost for Barca, who have started the season strongly following an off-season full of recruitment.
“It’s an important win at a difficult ground. We hadn’t won here for two seasons,” Xavi said.
“We created chances and we dominated. The three points were very important to stay at the top of the table.
“Sometimes we need to understand the last pass better, but I’m happy despite having not played an excellent game.”
