The Spanish news outlet have reported about Real Madrid's heavy interest in the 24-year-old midfielder. According to them, Toni Kroos has even recommended Stiller to his former club.
Stiller has been a transfer target for many teams ever since his meteoric rise with Stuttgart in the 2023/24 season. While the most recent year hasn't been quite as dominant from Stuttgart, they went from 2nd to 9th in the league, it proved they are able to win trophies (in the form of the DFB-Pokal) - Stiller definetly has that winner mentality.
The similarities between Kroos and Stiller are very obvious in the way they are playing, but it doesn't stop there: both players spent time at Bayern, where they were not fully appreciated - and Kroos was 24 years old (Stiller's current age) when he joined Real Madrid from the German team.
