Bayern crash in Mainz, and have decisions to make about the future

The Rekordmeister's defeat in Mainz opened the door to Bayer Leverkusen to get back into the title chase, and next week's date with RB Leipzig could do the same for the soda cans. What Matt, Nik, and Terry want to talk about though is the string of big names about to be out of contract at Säbener Strasse this summer. Is the club really set up for a successful changing of the guard?
