ESPN FC's Kasey Keller and Steve Cherundolo react to Gab Marcotti and Julien Laurens' takes on Bayern Munich's 5-2 comeback win against Mainz from the Gab & Juls podcast. Cherundolo admits that Bayern's Achilles' heel is their back line, but says it's all good if they can manage to keep scoring at their current blistering pace. Keller believes Manuel Neuer is not happy about Bayern Munich's inability to keep clean sheets, and questions how Hansi Flick will be able to shore up the defense. ✔ Subscribe to ESPN+: http://espnplus.com/soccer/youtube ✔ Subscribe to ESPN FC on YouTube: http://bit.ly/SUBSCRIBEtoESPNFC
