Luka Jovic has defended his scratchy form with Eintracht Frankfurt.
The 23-year-old, on loan from Real Madrid, scored three goals in his first two games after his January move, but has now gone six without finding the net.
"Failure is never an option for me," Jovic told BILD.
"Pressure is an essential part of every business, especially professional football."
Jovic takes confidence from what he has already achieved and believes in himself to rise to the next challenge.
"I like challenges, I love comparing myself with the best," he said.
"I know what I'm worth and what my qualities are.
"I'm only 23, I play in one of the best leagues in the world, in a great team and don't forget that I'm still a Real Madrid player."
