Crystal Palace have called Schalke about Ozan Kabak.
Schalke have drastically dropped their asking price for Kabak after their relegation from Bundesliga.
The Daily Mail says Palace are looking at signing the Turkey centre-back, who spent the second half of last season at Liverpool.
Palace also added defender Marc Guehi from Chelsea this week.
Liverpool had an option to buy Kabak for £18m but declined.
It is believed Kabak could be bought for around £12m.
Leicester and a number of Bundesliga clubs are interested in the 21-year-old.
