#3 RB Leipzig
If this article was about which Bundesliga teams that challenge Bayern in the long run, RB Leipzig would probably top this list, as the Red Bulls have accumulated a wealth of talent and have the necessary financial backing to become a powerhouse in Germany's top tier.
However, Leipzig will be facing a tumultuous season next year, with manager Ralph Hasenhüttl and Naby Keita both calling quits on their time with the Saxons. Both have been key figures in the club's recent top-flight success and will be extremely tough to replace
Additionally, Emil Forsberg's and Timo Werner's futures at the club are in doubt and a fantastic World Cup by either of the two will only spark more interest from foreign clubs.
Nevertheless, Leipzig's squad is young, hungry and has great potential. They are capable of beating anyone on their day, including Bayern, so why shouldn't they make a serious challenge for the top spot in the 2018/19 season?
