There is a race between Bayern Munich and Bayer Leverkusen, but when we look at both teams, Bayern Munich has the better squad. Bayern is not affected much by injuries, but this could have a bad impact on Leverkusen. If Bayer Leverkusen wins the championship this year, it will be more valuable than any other team's championship.
Yeah the league champion is just between the Bayern Munich and Bayern Leverkusen because they are the two champion of the German league this season and I don't see any club that could easily posed a threat against them so is obvious that they may likely win all there remaining matches because they are far better than any other clubs on this league.
But however in times of the right candidate for the league champion I would say is gonna be Bayern Leverkusen because in as much as Bayern Munich is very much in a good form Bayern Leverkusen is also better and considering some of there Bayern Munich injured players I don't think they stand a chance against Bayern Leverkusen and secondly wining this league is of a great importance to Bayern Leverkusen so they will putting all possible best to maintain there position on the league.
