According to The Mirror, Palace have added Boey to their January shortlist amid concerns over Daniel Munoz’s fitness.
It’s understood that Glasner is pushing the club to add players ahead of a hectic second half of the season and a disappointing summer transfer window.
Boey, who joined Bayern Munich from Galatasaray for a reported £30 million back in 2024 is said to be available for around £13 million.
The 25-year-old has had a bit part role at Bayern this season, starting just five of his nine Bundesliga appearances for the leaders.
