That win brings Madrid’s unbeaten start to the season to an end but they still top the table for now.
Zidane will be expecting his team to bounce back as their attention now turns to the Champions League when they face Shakhtar Donetsk on Wednesday.
Cadiz move to second in the table following that win and they remain unbeaten on the road this season. Next up for them is a visit from Villarreal.
Cadiz hold on in the second half to earn a 1-0 win over Real Madrid. The away side started the first half brightly and Negredo had an early chance cleared off the line by Ramos.
It was Lozano that scored the winning goal when he latched onto Negredo’s header and chipped the ball over Courtois and over the line. Madrid never let up the pressure in the second half, but they just couldn’t find a way past Cadiz.
Luka Jovic had a goal ruled out and Karim Benzema hit the crossbar, yet Madrid’s sluggish play was not enough to overcome Cadiz’s stubborn rearguard and maintain their winning run, as the Andalusian side held on for a famous triumph.
Prior to his injury, Ramos came to Madrid’s rescue inside two minutes, hooking Alvaro Negredo’s effort off the line.
Negredo went close with a header and Juan Cala tested Courtois with a shot as Cadiz kept up the pressure, though, and the visitors were rewarded for a brilliant start when Lozano prodded in over Madrid’s onrushing goalkeeper.
Lozano looked set to double his tally just after the half-hour, but Courtois made a fine save at his near post, though Madrid’s goalkeeper had a lucky escape when he dropped a cross which no Cadiz attacker could pounce on.
With four new players on, Madrid stepped up the tempo, though Vinicius’ wayward strike was the closest they came to troubling Cadiz early in the second half.
Vinicius should have restored parity after the hour, only to head wide from Toni Kroos’ left-wing cross, the Germany midfielder creating five chances as his team-mates struggled.
Jovic’s introduction looked to have sparked the comeback, yet the substitute’s goal was rightly disallowed for an offside from Benzema, who then struck the woodwork as Cadiz held firm to join Madrid and Granada on 10 points.
