In the Bundesliga at the moment there is only one intrigue left, whether Bayer will lose this season or not. And Stuttugart is one of the last strong rivals for Bayer this season, but in fact Bayer is already a champion and a possible defeat will not affect anything, unless Alonso and the team want to set this record, and go through the entire season without defeat. Stuttgart will have to play away, so it will be more difficult to do, but if this happens, the fans will forgive Bayer for this.
Bayern Leverkusen has 4 matches left in domestic league, 1 match in DFB Pokal Cup and two until three matches left in Europe League depend on qualifying to final stage or not. Actually Xabi Alonso success extending unbeaten record until 45 matches all competition and I believe with Bayern Leverkusen invisible record after winning Bundesliga tittle. In domestic league matches left, seems only VfB Stuttgart as strong or difficult opponent team and its not problem for Leverkusen how to defend the unbeaten record in this season.
Playing without huge pressure yet in domestic league after success winning Bundesliga trophy I think main reason why Bayern Leverkusen difficult for beating every matches left, last match Dortmund have leaded awhile but failed to defend their winning goals after the crucial come back from Bayern Leverkusen on the additional time, its fantastic with Bayern Leverkusen perform in this season always success scoring goals on late minutes.
