The former France global watched his side slip 16 points behind La Liga leaders Barcelona on Sunday as they were held to a 2-2 draw against Celta Vigo, which leaves them fourth in the current standings.
In front of fewer than 38,000 fans at the 81,000-capacity Santiago Bernabeu Stadium, Lucas Vazquez scored for Madrid in the 10th and 59th minutes, while Guillermo Fernandez got Numancia on the board in the 45th and 82nd. Real Madrid is above me, above everybody. "I can not look two or three years ahead because having the contract does not mean anything". We will work harder than ever now, in all senses. "We will not just give up".
"To be very clear I do not want any [new players]", he said. "It's not easy to earn a draw in this stadium".
The group's response was positive and, in fact, not only did the coach take the floor, but the players were self-critical, knowing that there is a lot of the season left and a lot at stake, such as the Copa del Rey and the Champions League. The second half was not good, but we're not going to go insane about it.
On Tuesday, Atletico Madrid eliminated third-division club Lleida, while Valencia beat Las Palmas.
On Thursday, Levante host Espanyol, Cadiz travel to Sevilla and holders Barcelona welcome Celta Vigo to the Nou Camp.
Formentera were unable to keep up the underdog trend, though, and after losing 3-1 to Alaves in the first leg, goals from Ermedin Demirovic and Alfonso Pedraza consigned them to a round-of-16 departure.
Earlier, Leganes reached the quarter-finals for the first time in their history after losing 2-1 at Villarreal but progressing on away goals after their 1-0 first-leg win at Butarque.
Despite losing 2-1 at Villarreal, who are now sixth in La Liga, Leganes progressed on away goals having won the first leg 1-0.
Denis Cheryshev scored Villarreal's victor with only a few minutes left.
He added: 'For me, we are recovering things and we will (recover) with my players and staying relaxed, without problems'.
In the previous round, Formentera had eliminated Athletic Bilbao, which has won the Copa del Rey 23 times.
