World footballer Robert Lewandowski has led FC Barcelona to their next victory in the Spanish championship with his sixth goal of the season in five games.

The Pole, who moved to Catalonia from FC Bayern Munich, scored in the 65th minute on Saturday and paved the way for the 4-0 (0-0) win at FC Cadiz three days before the Champions League reunion with Munich.

The 34-year-old also provided the template for Ansu Fati's goal in the 86th minute.

The other goals were scored by Frenkie de Jong (55') and Ousmane Dembele (90'+2').

FC Barcelona are still unbeaten after their fourth win and a draw and thus celebrated a successful dress rehearsal for the game in the premier class on Tuesday (9 p.m.) at Bayern.

With 13 points, Barca also initially took over the lead in the table from Real Madrid (12).

The record champions are only in action against Real Mallorca on Sunday (2 p.m. / DAZN).

Cadiz have now lost their five opening games, conceding 13 goals.

However, the game was overshadowed by a medical emergency involving a fan in the stands.

With the score of 2-0 for the Catalans, the game had to be interrupted for almost an hour.

FC Cadiz goalkeeper Jeremias Ledesma ran to the stands with a defibrillator and threw it on the stands.

A stretcher was later fetched from the cabin aisle and brought across the square to the grandstand.

The players of both teams stayed on the pitch for a total of almost 20 minutes before they were sent to the cabins by the referee.

It didn't start until 9:05 p.m.

What exactly happened was not initially known.
