The 23-year-old France international arrived in Bavaria from Juventus in the summer of 2015 and he is on his way to winning his fifth Bundesliga title already.
Coman has made 29 appearances in all competitions this season, scoring six goals but his progress has been hampered by fitness issues along the way.
Sane, who is valued at €100m by Manchester City, has been on Bayern Munich’s radar since last summer but a serious knee injury suffered at the start of the season scuppered any plans of a potential transfer.
Bayern Munich look set to revive their interest in the German international when the 2019/2020 season concludes.
Coman maintains he is used to the competition on the Bayern wings and is unperturbed by rumours linking Sane to the club.
"When I came to Bayern Munich we had Franck Ribery, Arjen Robben, Douglas Costa and me, and I was still a young player, compared to the legends Ribery and Robben," Coman told Bild.
"You can see that that's not a problem for me, it is better for the team if there are many players at this level.
"If Sane came, it would not be a problem! Except the club says to me that they no longer need me, but I think the club knows what it has in me.
"The situation of Leroy Sane has nothing to do with my own future."
