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.
The Werkself need a win in their penultimate match of the season at RB Leipzig on Monday evening (18:00 CEST) to keep their hopes of third place alive until the final day. After Eintracht Frankfurt lost on Saturday, Roberto Pätzold's side can close the gap on their rivals to two points and leave it all to play for next Sunday.

Down to fifth from fourth place despite taking an early lead: in the head-to-head for a Champions League spot, Bayer 04 were 1-0 up at VfB Stuttgart with just a minute played thanks to an Aleix Garcia strike, but ultimately lost 3-1 (2-1) to the more determined hosts. It meant the Swabians leapfrogged the Werkself in the Bundesliga table on the penultimate matchday.

Today sees Bayer 04 go head-to-head with their next direct rivals in the race for Champions League qualification (kick-off 15:30 CEST). Opponents Stuttgart are currently fifth in the table, level on points with the Werkself but one place below them due to a three-goal inferior goal difference. The Black and Reds' record at Bad Cannstatt tells a clearer story: they've not lost at VfB for over 16 years. One important factor in securing what would be three crucial points away from home is Leverkusen's strength on the counter-attack. Whilst Stuttgart are also extremely dangerous going forward, they will be without their captain. Today’s matchday news.
