VIDEO: Nagelsmann's first game as Bayern's new head coach

Julian Nagelsmann's start as Bayern boss didn't quite go to plan against Koln - check out the highlights here!

Without the majority of his first team playing, Bayern crashed to a 3-2 defeat in what ended up being a five-goal thriller. Bayern's Sieb opened the scoring on 6 minutes, before goals from Thielmann and Uth in quick succession turned it around for the hosts before the half hour mark. Zirkzee equalised after 34 minutes, as the sides went into the break all square. 

However, it was not to be for Nagelsmann on his debut, as Uth completed his brace just minutes before the hour mark, making it 3-2 on the day. Bayern will be looking to bounce back against Dutch champions Ajax in their next pre-season friendly on July 24.
