I agree with you that previously Leipzig could have been beaten by Wolfsburg, but in the next match Leipzig's chances of winning are very big because we have to look at the real strength that Leipzig has, even though they have been defeated, the performance of their current players is very ready to beat Wolfsburg in the match to come and I am quite confident that Leipzig can win to maintain their position.
Leipzig, who are already in the top four of the Bundesliga standings, will indeed try to win at home to Wolfsburg so that Leipzig cannot be overtaken by Dortmund, who in the next match will also try to win at home. So far Leipzig's performance has improved quite well and I am sure that the Leipzig players will continue to try to maintain their consistency in every match this season in order to put their team in the best zone in the Bundesliga this season.
Seeing Leipzig in the top 4 is normal and I am happy that this team does not lose its consistency every season. However, sometimes there are things that will prevent them from maintaining that position and Wolfsburg will indeed be quite a difficult opponent to beat. But in general, Leipzig can handle it and will continue to keep their distance from Dortmund's pursuit. The season is still long and I see it as just normal competition in the Bundesliga and maybe if Leipzig slips up, Dortmund will make good use of this to shift their position from the top 4.
Leipzig must make good use of their opportunities so as not to slip from their current position, because Dortmund is really waiting for Leipzig to experience defeat so that Dortmund can take over that position.
In my opinion, Wolsfburg is not a very difficult opponent for Leipzig, but Wolsfburg position is more superior because they are playing as the home team, even though Leipzig is playing away but seeing the opportunity Leipzig has a bigger chances than Wolsburg.
Even though they experienced defeat in their previous meeting in the cups DFB and Leipzig didn't manage to win the match but I'm sure Leipzig will playing seriously in the Bundesliga because Leipzig are trying to increase their points in the standing table.
