Miguel Torres admits he was "surprised" to be overlooked by Real Madrid coach Bernd Schuster for last week's victory at Villarreal.
"But now there are new players here and they're playing well. I have no alternative but to work hard in training and hope for my chance."
Torres, who began last season contracted to Real Madrid C, added: "I have been here since I was eight years old. My only aim is to succeed here and it was a great personal moment to sign a contract earlier this summer with the first team.
"The players from the juniors have a much more difficult time to play in the first team than those that come from outside the club."
