Zidane downplayed Madrid's recent setbacks, blaming critics for exaggerating the team's struggles and wanting to create turmoil at the club.
Real president Florentino Perez is looking to overhaul his squad after a season of disappointment so far, with boss Zineddine Zidane also being tipped to leave at the end of the season.
La Liga giants Real Madrid are reportedly seriously considering a move Manchester City attacker Raheem Sterling.
After a year in which the team won a club record five different trophies, a 3-0 Clasico defeat at home to Barcelona was also not taken well by fans before the winter break.
Lucas Vazquez scored twice as Real Madrid booked their place in the quarter-finals of the Copa del Rey following a 2-2 second-leg draw with Numancia at the Bernabeu.
"You can analyze it any way you want it, saying it is a crisis or whatever, but we are here to find solutions", said.
The source said: "Nothing is imminent, but Sterling is in Madrid's thoughts". I don't see it like that. "I have to try to get each one of them to give a little bit more".
Los Blancos do have a game in hand on Ernesto Valverde's rampant side, although they face a stern test when they welcome sixth-placed Villareal - just four points behind them in the table - on Saturday evening.
Zidane chose to rest some of his big players in the clash against Numancia keeping the La Liga and Champions League campaigns in mind.
In the Champions League they were beaten convincingly at Wembley by Tottenham and failed to top the group leaving them with a very hard last-16 qualifier against Paris Saint-Germain on February 14 at the Santiago Bernabeu. "We can improve in all areas. That's what's important, and recently it has been hard to win matches". "I think there are always up and downs throughout the season and I hope Real Madrid continue to fight for the goals they have this season". He will say: "'If you sign, I will sign, ' and I say the same to him!" the goalkeeper told the Evening Standard earlier this month.
