We still don't know if Dortmund can take back the first place in the league or not because in the remaining three games, nine points can change and we know that's enough for Dortmund to be the champions of this league or lose everything they worked hard for it, but I expect to see Bayern Munich losing points and give Drtomund the opportunity until the end of this season.
I think Bayern Munich's match against Leipzig will have a decisive role in the league championship. Bayern Munich will most likely win their other matches. However, if they win that match, they can complete the remaining matches of the season without loss and become champions.
Bayern Munich have risked their championship chances this season due to the mistakes of club managers. I think Lewandowski leaving the team was a normal development. However, it was an unacceptable development that Bayern Munich managers did not sign a striker with the number 9 feature to replace him. If they win a championship under the current circumstances, I think they'd have done a really good job.
