The U21 European Champion, under contract at Bayer 04 to 30 June 2024, will strengthen the 2007 champions to the end of the current season, which in Norway runs to the middle of December.
"It's important for Lennart to gain match practice as a first choice keeper," said Bayer 04 sporting director Simon Rolfes. "He can develop his game in Bergen and the experience abroad will also give him an additional stimulus."

There were celebrations among those in black and red at the RheinEnergieSTADION. On Matchday 9 of the 2026/27 Bundesliga season, the Werkself beat 1. FC Köln 2-0 and registered their sixth successive win in the derby. Aleix Garcia put Bayer 04 in front after just seven minutes with a direct free kick. Leverkusen played with discipline and energy after that and didn't allow some fierce challenges to unsettle them. Patrik Schick made it 2-0 in the 86th minute, and Said El Mala's goal in stoppage time for Köln proved nothing more than consolation. Jonas Hofmann crowned the derby win with his 100th appearance for the club.
