Guler arrived at Real Madrid from Turkish giants Fenerbahce in the summer of 2023 for €20m (£16.5m), but has not been a regular given the depth of superstars at the club.
Despite limited game time though, Guler still performed extraordinarily well in his debut season at the Bernabeu, scoring six La Liga goals in just 330 minutes of playing time last season.
As one of the finest young players in the world, Guler is a regular for Turkey, and shone during Euro 2024, scoring one of the Goals of the Tournament against Georgia in the group stage.
Since bursting out on the European stage, Guler has since featured more often for Los Blancos, already making 18 appearances this season, six more than the whole of last season.
Real Madrid issue 'hands off' warning on Guler
Reports earlier this week from Sky Sports Germany correspondent Florian Plettenberg saw him claim that Leverkusen were keeping tabs on Guler over a potential move next summer.
It was believed Die Werkself knew that a deal could not happen during the January transfer window, but would have pursued one at the end of the season, if the young Turk was seeking regular playing time.
The report also stated that Leverkusen were one of the clubs that were in for Guler before he made the high-profile move to the Spanish giants from Fenerbahce.
However, Fabrizio Romano claims that Leverkusen, and other potential clubs interested in the player, have been told that no transfer involving Guler will happen anytime soon.
Guler is said to be very happy at the Bernabeu, and the feeling is reciprocated by the club, who see him as an indispensable player both for the present and the future.
Real Madrid keen to keep Guler for the foreseeable future
Reports which stated that Guler would not leave under any circumstances in the January window, permanently or on loan, would most likely be because of Real's threadbare squad that has suffered many injuries this season.
Kylian Mbappe was the most recent player to break down with an issue in the 3-2 win over Atalanta on Tuesday.
That comes after Vinicius Junior and Rodrygo have also spent time on the sidelines this season, meaning Carlo Ancelotti's has infrequently had a full attacking roster to choose from.
However, the undoubted potential that Guler possesses seems to be the factor behind why Los Blancos are so unwilling to listen to any offers for the 19-year-old.
Guler was only given five minutes in Bergamo this week, but had started three of the previous five games, assisting in the win over Leganes, and scoring the second goal away to Girona last weekend.
