The 24-year-old made the move to Bernabeu from Monaco in July 2022, and he has represented the reigning European and Spanish champions on 93 occasions, scoring three goals and registering five assists in the process.
Liverpool were in the running to sign Tchouameni from Monaco in 2022, while Arsenal are said to be long-term admirers of the France international.
There have been suggestions that Real Madrid would be open to selling the Frenchman if a big-money offer were to arrive, but Romano has shut down those rumours, putting the midfielder's chances of leaving Bernabeu at "zero".
"We saw these rumours in England and we keep receiving many questions on Tchouameni because the summer transfer window just closed. Many people raised rumours about Liverpool, Arsenal, Tchouameni in 2025," Romano said on his Here We Go podcast.
Real Madrid 'not interested' in selling Tchouameni
"I wanted to clarify something for 2024, 2025, 2026, whenever. The intention of Aurelien Tchouameni is to stay in Real Madrid.
"The intention of Real Madrid is to keep Aurelien Tchouameni as a crucial player for that project. For present and future. They are in love with Tchouameni; with the player, with the professional.
"How he acted in the centre-back position was something really appreciated by the technical staff at Real Madrid. So it's absolutely not even considered for Real Madrid to sell Aurelien Tchouameni. The situation is perfect between the club and player.
"I can guarantee at the moment, despite all the rumours, we know how many clubs can appreciate a top player like Tchouameni. But in terms of concrete possibilities for him to leave Madrid - at the moment, zero."
Tchouameni could be needed in central defence vs. Real Sociedad
Tchouameni withdrew from the recent France squad due to a foot problem, but he is expected to be fit to face Real Sociedad next weekend.
The Frenchman could be needed in the middle of the defence for Real Madrid's next match, as Eder Militao suffered a thigh issue while on international duty with Brazil.
David Alaba remains out with a long-term knee problem, while Jesus Vallejo is down the pecking order, so Tchouameni or Dani Carvajal are likely to play alongside Antonio Rudiger in the middle of the defence against Real Sociedad.
Tchouameni has already made five appearances for Real Madrid this season in his preferred holding midfield role, but he operated as a centre-back on a number of occasions last term due to the injury problems for Alaba and Militao.
Despite their current issues at the back, Real Madrid will reportedly not be moving for a new central defender during the January transfer window.
