Younes is preparing to meet Champions League opponents RB Salzburg.
“I am happy that the Coach put his faith in me. We are a fantastic squad and each of us want to prove ourselves," he said.
“We respect Salzburg, they are a strong side full of young players, they play at a high tempo and press well. We can't hide from the dangers of the game and must give our all.
“There is a lot more pressure at Napoli and I am improving here in every way, during training and matches."
