Real Madrid coach Zinedine Zidane is ready to turn up the heat on Marcelo.

Regarded as Real's clear first-choice left-back, Marcelo suddenly finds his status under threat from summer arrival Theo Hernandez.

Diario Sport says Zidane is ready to introduce Theo this month, bowled over by his training ground form.

While Marcelo has been away with the Brazil squad, Theo has spent international week working with Zidane at Valdebebas.

The defender has impressed his coach with his form and attitude, which has been relayed to management. Zidane feels Theo is already in a position to push Marcelo for a starting place.
