Jannik Mause is currently on loan at Rot-Weiss Essen from 1. FC Kaiserslautern. Rot-Weiss Essen has a purchase option set at 600,000 EUR, but local newspaper WAZ reports that this sum is considered 'almost utopian' for the third-division club, making a permanent transfer unlikely. Mause is therefore expected to return to 1. FC Kaiserslautern next year.

Jannik Mause joins Rot-Weiss Essen on loan from 1. FC Kaiserslautern to gain more playtime due to high competition at his parent club. Mause, the 2023/24 top scorer in the 3rd division, aims to gain match practice and return stronger to Kaiserslautern. Rot-Weiss Essen values his qualities and versatility, hoping he adds depth to their offensive lineup. Mause, who struggled last season at SpVgg Greuther Fürth, is eager to prove himself and might debut against Alemannia Aachen this Sunday.
