The 20-year-old has impressed during spells with Genk and more recently Leverkusen to earn links with a wide range of clubs across the continent.
Asked specifically about those three clubs, Bailey told German outlet Kicker: "There's concrete interest. What I can say is that my full focus is on developing myself as a young player. If a club wants me, my management and Bayer will take care of it.
"Bayer want to play for the title. Bayern Munich is one of the three strongest teams in the world for me, but in football you never know."
Real Madrid, Bayern and Arsenal have also previously been tipped to move for the £52m-rated wide midfielder.
