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."

After a goalless and at times evenly-matched first half, Bayer 04's U19s ultimately suffered a heavy defeat at Manchester City. Coach Kevin Brok's depleted side - including five players who were part of the senior squad for the Champions League game in the evening - lost 6-0 on Matchday 5 of the UEFA Youth League.
