The Colombia international has been a crucial player for Palace following his January 2024 arrival from Belgian side Genk with four Premier League goals scored in back-to-back seasons.
As a rampaging right-back for Oliver Glasner, he also won the FA Cup and UEFA Conference League, but new boss Pierre Sage appears to be moving in a different direction in 2026/27.
Oscar Mingueza and Anan Khalaili have both joined the club this summer and that puts Munoz's starting place at Selhurst Park under real threat.
He is under contract with the Eagles until 2028 - with Palace also holding an option to extend that by a further year - but the 30-year-old is reportedly on Tottenham's transfer radar.
Roberto De Zerbi is rebuilding his Spurs defence, and as per the latest update from Football Insider, he wants Munoz to replace the departed Djed Spence.
However, despite De Zerbi's eagerness to sign him, Munoz is unconvinced over the move, as Pedro Porro is well-established as first-choice at right-back, with the Spaniard also signing a long-term extension before the 2026 FIFA World Cup.
With no European football this season, De Zerbi may struggle to persuade Munoz on possible game time, and that may block a formal bid.
