Leverkusen always refused to lose, there were many matches they scored a goal near minutes 90 or injury time.
Yeah the upcoming match against Stuttgart will be interesting to watch, this season both Leverkusen and Stuttgart have improved a lot among other teams in Bundesliga. I think it will end in draw, but I won't really surprised if Leverkusen lose in this match.
Losing is never in their mind, winning or winning is their top priority. Bayern Munich couldn't withstand the pressure coming in from Bayer Leverkusen this season, they kept on a consistent performance, flogging every opponents they came acrossed without stress. Bayer Leverkusen tried and absorbed pressure, winning have always been the top goal for Xabi Alonso. He knows the challenges involved and have fully equipped his team to exert winning mentality. Bayer Leverkusen have been their very best, maintaining unbeaten run till this very moment.
