A biggest surprise in this season is Bayer Leverkusen as they are improving more from the past season and currently stays at a first position with 31 points, 2 points more than Bayern Munich. It's no other word than very impressive performance from them.
Another surprise is Stuttgart as they have a first season in top range of Bundesliga after many years. Leipzig at least have been regularly appearing in top range of Bundesliga recent seasons. Their performance in this season is good especially after they sold their most important defender, Gvardiol to Manchester City in the summer transfer season. Without the Croatian defender, they still maintain a strong defense system with only 18 conceded goals in Bundesliga. About this conceded goal aspect, Stuttgart is a big surprise with only 15 conceded goals so far and it is a basement for their success so far.
I don't think surprised with Bayern Leverkusen achievement in this season keep unbeaten trend because Xabi Alonso have made special result last season after success finish on 6th standings where first time arrived Leverkusen on relegation zone. But difference with Stuttgart make surprised performance in this season although they have loss 3 of 11 matches but success manage on third place and dropped position with teams dominance on top fourth such as Dortmund, Union Berlin and RB Leipzig.
Stuttgart have ratio above 2.7 goals scoring each match regarding they have scored 29 goals and their center forward Serhou Guirassy compete on top goals scorer standing remaining 2 goals from Harry Kane, he was scored 15 goals of 9 matches and Stuttgart will be new teams for compete Bayern Leverkusen and Bayern Munich fighting in tittle race.
It's time for the Leverkusen team to chase the Bundesliga title this season because while competing in the Bundesliga they have never succeeded in winning the title. Seeing the significant improvement in the performance of the Leverkusen team this season provides an opportunity for them to win the title, especially now that they are still very firmly at the top of the standings and have not been defeated during the match and they are also playing very well under the control of Xabi Alonso so there are high hopes for Leverkusen to become one of the teams that has the opportunity to lift the Bundesliga trophy.
