Former Bayern Munich center Wagner is now a commentator on Sky Sports in Germany. In a recent TV show, Wagner believed that Dortmund and Leipzig could pose a threat to Bayern.
Wagner said on the TV show: "When Bayern is tight and they do a good job of reinforcement, it will be difficult for other Bundesliga teams to pose a real threat to them."
But at the same time Wagner also believes that Dortmund and Leipzig can pose a threat to Bayern in the future. "Dortmund has a very talented team. If these young players can stay together, then Dortmund will definitely pose a threat to Bayern."
In the previous season, Dortmund had been overtaken by Bayern with the points leading. Wagner said: "Normally, this kind of situation is not allowed to happen. I can't say exactly where there is a problem because I am not here. But I still believe that Dortmund and Leipzig led by Nagelsmann can give Bayern Bring threats."
