I don't see what is complex about predicting the winning of the Bundesliga this season as i know that Bayern Munic will win the league and it is not subject to argument. They might have had some challenges but that is not only reserved for them because Bayern Leverkusen have also had their own challenges that made them unable to win some easy matches. The point difference between Bayern Munich and Bayern Leverkusen is enough for Bayern Munic to win the league.
So far, Bayern Muniches performance has actually been enough to make them appear like they have got that better chance to win the Bundesliga this season but then i always see it that until we have gotten passed half season, then we cannot say that a particular team has gotten the chance alone against other teams in the title race. by mid season we could then see the point differences and then see if its enough to sustain the team till the end of the season such that they can still have that advantage over every other team in the league.
Bayern Munich full strength football team is one of greatest team of Bundesliga and millions of people have an eye on that team because their performance is on the next level and they are most favorite team for win the Bundesliga. The players of that team are in full confidence because they won many matches and they know that they could win the next matches and have first position which is very important thing for that team and team is getting more confidence when seeing them at top position. Leverkusen full strength football team could give tough time to Bayern Munich because their performance is also good and that team has good points on the table and won many matches in the Bundesliga and if Bayern Munich did any mistake then Leverkusen will be winner of Bundesliga.
