Rayo Vallecano teen Pablo Munoz is attracting interest from Barcelona and Real Madrid.
The 19 year-old midfielder is regarded among Spain's brightest young talents.
Munoz scored 19 goals from midfield for Rayo's youth team last season and has been watched by Barca over the past two years.
Sport says Real Madrid are also keen on Munoz ahead of the January market.
In 2020 Barça beat Real Madrid for Fabián Luzzi, also signed from Rayo, and hope to do the same with Muñoz.
