Atleticos goals were scored by: Joao Felix (twice), Marcos Llorente and Luis Suarez.
Atletico increased its tally to 17 points in first place temporarily, despite playing only 7 games and keeping two postponed matches in its balance.
Kadesh stuck at 14 points, in sixth place.
Atletico is the only club that has not suffered a defeat in the Spanish League so far this season.
It suffices to win Atletico Madrid in one postponed game in order to be the only leader in the Spanish League, as it has only squandered 4 points until the moment.
And Atletico reached 23 consecutive matches without defeat in the Spanish League, which is the fourth team in the history of the competition to reach this number after Real Madrid, Barcelona and Real Sociedad.
On the other hand, Cadiz’s superstar streak was stopped outside his stadium, as he started the league with four foreign victories without shaking his own net, a series that was destroyed by Diego Simeone’s men.
Atletico opened the scoring early in the eighth minute with Joao Felix headed by Marcos Llorente’s cross, who took advantage of a wrong exit from goalkeeper Conan Ledesma.
Llorente, who joined the Spanish national team for the first time, celebrated optimally, adding the second goal with a powerful shot from inside the penalty area in the 22nd minute, which Ledesma failed to confront again.
In the second half, Suarez scored in the 51st minute after exchanging the ball with Felix, but the flag was raised, announcing an offside.
With the return to video technology, it was revealed that Suarez was in a legitimate position, so the goal was calculated and the former Barcelona striker raised his score to 5 goals in the league this season.
Felix finally concluded the goals himself after a beautiful pass from substitute Angel Martin Correa in the first minute of injury time.
Felix also reached 5 goals in the top scorer in the league, with the participation of Suarez and Mikel Uyarzabal, captain of Real Sociedad.
Felix scored a total of 7 goals this season and scored 3 goals in 10 matches he played with Atletico Madrid.
