I don’t think Wolfsburg has any squad to win the title. They have performed well in 3 matches. In particular, their performance against RB Leipzig is very commendable. But there are still strong teams like Bayern Munich, Leverkuse and Dortmund to face. If Wolfsburg can beat them, I would say they could claim the title this season.
Wolfsburg can have a few matches or a few months with very good results but they won't be able to keep it up in a full season. Even Dortmund can not do it in many seasons to beat Bayern Munich. So I don't think Wolfsburg will be able to do it. They have to show that they are better than Dortmund and Leverkusen before thinking of beating Bayern.
Even though Wolfsburg have played quite well and consistently in their three matches this season, this cannot guarantee that Wolfsburg will be a contender for the title this season, I think Wolfsburg should be consistent when they face a team as big as Bayern or Dortmund and if their can win against these teams, of course, the motivation of the players will increase and the goal of champions might be realistic for them this season, I think Wolfsburg's real test will be Bayern Munich and Dortmund.
It's just early of this season. I congratulate them for three good matches but as said, it is early of the season. They have more than 30 matches in Bundesliga to show and with their squad, any injury on key players will bring serious troubles to their tactic, performance and result.
Wolfsburg will have to beat Leverkusen to become the third biggest club in Bundesliga, at least in this season. Then they can think of Dortmund or Bayern.
