Tena's case is more straightforward, as he is eligible to be transferred without a fee due to his age. On the other hand, Piqueras is still under 16 and has not signed a professional contract. His agents are in discussions with Atletico Madrid about a possible transfer.
Both players have been part of Valencia's academy since a young age, with Tena joining in 2008 and Piqueras in 2009. Their potential move to Atletico Madrid could be a significant development in the transfer market this summer.
