The league is still very open though I'm not expecting Bayern Munich to drop points to the extend of Bayer Leverkusen catching up with them this season, Bayern Munich has an advantage to extend the point to 12 when they play against Leverkusen, if they are able to defeat them then they stand a better chance of winning the league title this season.
Bayern Munich is already doing so well in the league more than any other team I think they have more good chances of extending the lead now that Leverkusen is struggling to stay in good shape, Bayern Munich will be looking forward to winning double this season if they can win the champions League then it will be good season for Kompany I believe he's got the league title in the bag already.
Even though the match between them and Leverkusen ends in a draw I think it isn't still a bad result hence we already know that leverkusen isnt just a small team, Bayern needs to build up very formidable force to maintain consistency in their winning streak, note there match with Leverkusen is not what decide who lift the trophy this season though it is also a good thing for them if they win that encounter because it may strengthen them more and give them more confidence in tackling their remaining league events of the season, am very much happy that you said bayern is performing very well this season, in the aspect of the match involving Leverkusen and Bayern, i must tel you the truth that such football event wouldn't be a work over for any of the teams because both teams are the major contenders of the league title as such none of them will want to drop points easily so i see there meeting to be a tough one.
Your conclusions are right but it will take very much effort for Bayern to achieve such a double success though it all depends on how ready they are to make such a reality.
