The Amsterdam club have set their sights on Spain Under-21 defender, after baulking at AZ's asking price for Finland international Niklas Moisander
The Belgian left the Eredivisie champions this summer to sample the Premier League with Tottenham, and the Amsterdam club had earmarked AZ centre-back Niklas Moisander as his replacement.
However, their interest in Moisander has cooled due to €6 million price tag placed on the Finn, and the Dutch giants are now considering making a move for Barcelona 'B' star Muniesa.
"The interest in Muniesa is correct, but nothing is yet decided," Overmars said according to De Telegraaf.
Muniesa has represented Spain at Under-21 level on two occasions, and made 24 league appearances for Barcelona's second string team last term.
