It doesn't seem like that. This season Leverkusen has scored 46 goals and Munich has scored 49 goals which means they both have the same number of goals in the League. This indicates that Leverkusen has not dominated the Bundesliga and as we know Munich is very strong and they could be the ones who will win the title this season. We can see last season where they competed very competitively with Dortmund but in the end they won with the same points but Munich had a better goal difference.
I think this is the one of the advantages and edge Bayern Munich has been able to maintain recently despite their form fluctuating recently but then I think priority judgement for winners of the league is usually placed on points which is Leverkusen's edge. They don't have to score thousands of goals to win but need the points.
If Bayern Leverkusen finishes with the highest point amongst all teams in the league and Bayern Munich finishes with the highest number of goals but are still behind Leverkusen in point, definitely Leverkusen will be declared winners because they have got the highest point meanwhile Bayern Munich will only be recognized for their goals so I still think currently Leverkusen still have better chance until they drop points so much so that they no longer are able to lead with points but in a situation whereby both team finishes with same points, that's when the goals difference will favour Bayern Munich, I think it will be better if Leverkusen is able to get more goals and be ahead in every aspect.
getting more goals should not be Leverkusen aim but just to get the entire 3 point and that's enough remember Spain won the 2010 World Cup with just 8 goals all they need is to defend well, take the lead and win each match that is consistency trashing team 8 goals and ten losing or drawing other suppose winning matches is not needed. Leverkusen just have to stay fit and continue what they are doing pray they are consistent enough to win the league
