Players who suffer injuries will certainly greatly affect the team's performance, although it is not comprehensive, there are definitely things that make them lose control. I'm sure there will be a time when this team experiences this and until that happens they will be fine without any problems. The rivalry between Leverkusen and Bayern Munich will always be a hot topic of conversation and both of them are the teams most likely to win. Dortmund this time is not like the previous season and it looks like they will not participate in the race for the title considering their erratic performance.
The rivalry of these clubs for the Bundesliga title are on different titles this season, we just pray and hope for our favorite clubs to win games and lift major trophies. Borrusia Dortmund doesn't suit into the high competitive standards set up by Leverkusen and Munich. A club performance depends on the key players abilities and the tactics implemented by the coach. Bayer Leverkusen and Bayern Munich players doesn't sustained any critical injuries and if they do, the club have backup players and they're holding for for incredible performance this season.
