The German bundesliga is one league I don't too fancy because of it boringness.They allow only Bayern to be winning the league year in year out without giving them any tough competition.It has always been like that,that Bayern will end up winning the league at the end of the day,but it is bad that the other teams that were supposed to give them firm threat and competition are not giving them,therefore,it has made the league boring.
the only team that I thought were going to challenge them for that trophy was Dortmund,but instead,Dortmund choose to sell their best players every season,to give Bayern the power to dominate them well.
No wonder you think that the Bundesliga is a boring league because Bayern Munich's dominance here is very high. I too am one of those people who think this league is boring for title fights. I prefer to see the Bundesliga in competition for the top 4 positions, because the competition there is still a lot of teams that are able to provide competitive competition.
You are right that Borussia Dormund is a team that can actually put great pressure on Bayern Munich. But if they continue to only think about money then they will never achieve great success in this Bundesliga.
Bayern Munich is unanimously dominant power of Bundesliga with in last few years there was some competition from Borussia Dortmund but in this season after poor start they are again at the top of league table, but Dortmund is badly struggling due to bad decisions and injuries issue hopefully they will try to fight back after having suitable replacements in January window but in this season we have positive change with few teams are doing good job and having fight for the top ranks like Freiburg, Leipzig and Frankfurt which mean things are improving which is good change.
Union Berlin which was leading table now at fifth spot hopefully they will also try to come back at top ranks even now it's tough time for them with they need to increase quality and performance which is not possible without few quality players, but surely things will be changed in coming days for the top ranks which is good.
