Felix Irorere will join the Borussia Dortmund U23s from second-tier Karlsruher SC on a free transfer and will strengthen coach Jan Zimmermann's team from next season onwards.

At 1.95 metres, the Franco-German is likely to be one of the tallest players in the league. "We're delighted to have Felix, who will add a new dimension to our game thanks to his height alone," commented Ingo Preuß, the sporting director of the U23s. The 20-year-old defender came through the ranks in the Eintracht Frankfurt youth system and scored five goals in 24 appearances for the U19s. Following his time at the SGE academy, he joined Karlsruher SC in 2021.
