Tottenham Hotspur has blocked Real Madrid's pursuit of right-back Pedro Porro by refusing to negotiate a summer transfer, according to reports.
The English Premier League club intends to keep the Spanish defender as a key part of their long-term project in North London.
Real Madrid is searching for defensive reinforcements following the departure of veteran full-back Dani Carvajal.
Club officials have evaluated multiple candidates, with Porro emerging as a preferred but increasingly complicated target.
Transfer market specialist Fabrizio Romano reports that Tottenham has no intention of selling the defender despite interest from elite clubs, including Manchester City.
The North London hierarchy and new manager Roberto De Zerbi view Porro as indispensable for the upcoming season.
De Zerbi considers the Spanish full-back a "crucial piece" of his squad.
This firm stance has halted immediate negotiations, prompting Real Madrid to shift focus toward more attainable targets.
Inter Milan defender Denzel Dumfries remains a prominent alternative on their shortlist.
Real Madrid is aware that Dumfries has a €25 million release clause in his contract, which eliminates the need for lengthy club-to-club negotiations with Inter.
A potential deal for the Dutch international would depend on securing a personal agreement with the player.
