Rayo Vallecano boss Paco Jemez has praised Alberto Bueno after the Spaniard continued his fine scoring form against Granada at the weekend.
Bueno's brace in Rayo's 3-1 victory moved him onto 15 league goals for the season, bringing his top-flight tally for the club to 26.
"I told [Alberto] to try finishing the season with more than 20 goals. When you have history in your hands, even with a humble team, you have to be courageous," Jemez told reporters.
"It's very hard to do what he's done. He's a player who fights [for every ball], and his teammates have helped him. I'm glad to be coaching a player who would fit in many of the top teams. We'll soon see him at one."
A number of European clubs are said to be monitoring the former Real Madrid youngster.
