The 27-year-old is in the final year of his contract with RB Leipzig, and he seemingly does not want to put pen to paper on a new deal.
As a result, Leipzig want to get any cash in for him this summer, in order to avoid the possibility of him leaving the club on a free next summer.
Arsenal and Spurs have been heavily linked with the midfielder, while Bayern Munich have also emerged as candidates to land his signature during this transfer window.
According to German television channel Sport1 (via Florian Plettenberg), Leipzig will not stop Sabitzer from joining Bayern Munich if they receive an offer in the range of €15 million to €18 million.
If Sabitzer does get a move to Bayern Munich, he might not be as much of an integral player as he currently is at Leipzig, with the German giants having plenty of midfielders playing in the same position.
While the German club were willing to allow Sabitzer to see out the rest of his contract earlier during this transfer window, Leipzig are now prepared to sell him in order to get something for him this summer.
Ever since he joined from Rapid Wien in 2014, Sabitzer has been a key player for Leipzig, making 227 appearances for the club, with 39 of them coming last season in all competitions, scoring nine goals and providing seven assists.
Leipzig are relaxed about the situation, as they feel that new manager Jesse Marsch has plenty of alternatives in that position, including the likes of Dani Olmo, Dominik Szoboszlai, Kevin Kampl, Amadou Haidara and Konrad Laimer.
While Bayern Munich are working to try and get a deal sorted out for Sabitzer, it remains to be seen if Arsenal and Spurs will try to act on their interest in the Austrian international, with Leipzig being willing to negotiate for such a low fee.
Both Arsenal and Spurs are chasing some new midfield options, with them being light in midfield due to several central midfielders at both clubs being poised for moves away, including Lucas Torreira and Moussa Sissoko at Arsenal and Spurs respectively.
