Real Madrid youth coach Guti says victory over PSG silenced the doubters a fortnight ago.
Real went into the first-leg of their Champions League as underdogs, but proved a class above their opponents as they won 3-1.
Guti, who was linked with Zinedine Zidane's job going into the game, says the result silenced their critics.
"Real Madrid has shut mouths," he told Cadena Ser.
"PSG are an excellent team and have put Madrid in trouble, but they have not been up to it. It's a good result, but we will not relax."
