"To be a supersub is mentally hard," he said. "The Liverpool fans are happy with me as a substitute, but I didn't get a chance yet as starter. I have never played three matches in a row from the start.
"It's clear I have enough qualities to be in the starting eleven of Liverpool, but when you never get a real chance it's getting difficult.
"I'm not the type of player who gives up. Benitez told me he sees me as a starter in the Liverpool eleven in the future. At this time I still believe him.
"To be underestimated is my biggest motivation. I will take revenge in different ways."
