Granada forward Jona has reportedly emerged as a transfer target for both Real Madrid Castilla and Barcelona B.
The 24-year-old, who is currently on loan at Real Jaen, has netted 10 times in all competitions this season, with a number of clubs understood to be monitoring his progress.
However, according to AS, Granada are not prepared to discuss any reported interest, with the forward earmarked for a spot in their first team next season.
Jona is yet to make a first-team appearance for his parent club.
