The Spain Under-20 prospect has voiced his admiration for the Portugal star and is hopeful of breaking into the first team at the Santiago Bernabeu next season
The 20-year-old impressed for the club's Castilla side in 2012-13 as he netted 22 goals in the Segunda Division and he has set his sights on a spot in the first team next season.
"I have liked a lot of players; the Brazilian Ronaldo, Ronaldinho, but my favorite is Cristiano Ronaldo. I like being compared to him," the Spain Under-20 star told Marca. "I love his drive. He never gets tired of scoring goals. He always wants more.
"The club president is happy with me. I hope to reach an agreement and stay at the club. I really want to play in the first-team."
Jese made his official debut against Ponferradina in 2011-12, but has since been unable to secure regular first team action.
