The Under-17 World Cup has begun in Brazil and Argentina will start their campaign against Spain on Monday featuring Matias Palacios, one of Pablo Aimar's biggest stars.
Barcelona are among the clubs who will be monitoring him closely as the San Lorenzo man takes to one of the biggest stages.
Aimar recognised the midfielder as one of the most promising players in his side and expects an exciting future from 'El Payasito'.
According to MARCA Claro sources, San Lorenzo are aware of the interest from European clubs including Barcelona but do not want to sell him at any price.
Italian clubs are also believed to be interested and many will be monitoring his performances closely in Brazil after he broke into the San Lorenzo first team earlier this year.
