This match will be the match that we will use to examine the quality of both teams and who is better than the other because they are both strong teams and rivals.
Leverkusen isn't a match for Bayern in their current form, so unless a miracle happens, I don't see the chances of them toppling the big steppers and taking their position. Bayern, the team of the top bundesliga table has much more goal difference than anyone else and that's point 1 proven.
Nevertheless, i see the coming match to be a tough one as everyone is prepared to win. We all know the capability of each of these teams but, who knows?
Kompany was able to improve the team's performance when he took over as manager but that doesn't mean that it is a guarantee that Bayern Munich will win Leverkusen by weekend since Leverkusen is still in form. Don't underestimate Xabi Alonso.
