All four were prominent once again in midweek as Madrid hammered Deportivo La Coruna 6-2 after Zidane made nine changes to the team that started the Clasico defeat to Barcelona.
They may get another chance on Saturday when Zidane's men face Valencia at Santiago Bernabeu and will aim to give the Frenchman food for thought before Tuesday's Champions League semi-final against Atletico Madrid.
The likelihood is the former Juventus midfielder will return to his 'A team' against their cross-city rivals but he remained adamant everyone will have a part to play as Madrid challenge for honours on domestic and continental fronts.
He told a news conference: "I do not think it's unjust, I don't think that's how I behave. It's the complete opposite. I have immense respect for my players.
"At other clubs, for example, the reserves do not play a minute except in emergencies.
