The 18-year-old has worn the Black and Red shirt since 2013 and he has made 16 appearances for the Bayer 04 U19s in the current U19 Bundesliga West campaign. He has also been very much in demand with the Germany youth teams. Boller (pictured above in the middle with Lucas Alario and Sam Schreck in the game at Heidenheim) has earned 15 caps for the Germany U17 team and he was a first choice in central defence at the 2017 European Championships in Croatia as well as the World Cup in the same year in India. He played alongside Kai Havertz in the Bayer 04 U17s in 2016 when they won the Germany U17 championships with a 2-0 victory over Borussia Dortmund in the final.
In Germany, the temperatures are currently around zero, leaving even professional footballers freezing - but not the Bayer 04 Women. Roberto Pätzold's team have fled the cold to the south and are preparing for the second half of the season at a training camp in the Algarve, almost 2,000 kilometres away from home as the crow flies. The Leverkusen squad landed in Faro on Saturday morning and have already completed the first three training sessions over the weekend.

It was a disappointing Saturday night. The Werkself lost 4-1 to VfB Stuttgart to start the new year on Bundesliga matchday 16 in 2025/26, a result that left both players and fans disappointed. "We played without any passion," said Alejandro Grimaldo honestly afterwards. Teammate Jarell Quansah was even more self-critical, emphasising: "We were miles off it in the first half. You can't put in a performance like that, especially in front of our own fans and I can only apologise to them, to be honest." Read on for the reaction, facts and stats from the clash with VfB Stuttgart in the Werkself review.
