The Real Betis man is a target for both clubs in their hunt for a new defender.
The window is now looming nearer and nearer and it seems Everton are getting their targets lined up. One such player is said to be Cristiano Piccini.
The Italian helped Betis to promotion last season whilst on a loan deal from Fiorentina and made the move permanent in the summer.
He has continued that good form for the Verdiblancos in the Spanish top-flight and that has attracted the suitors mentioned.
The 23-year-old is a right-back - a position where Everton need to add cover.
Seamus Coleman is currently their only recognised right-back. Tony Hibbert is perpetually injured and Tyias Browning is a centre-back by-trade.
Piccini would therefore be a brilliant addition to the side but there is no doubt Porto will be worthy adversaries in the transfer market.
