Interest in the Bundesliga had decreased because it had not been competitive for years. It was seen as a simple league that Bayern Munich always won, whereas Dortmund had many players that it brought to world football. Now there will be 2 or 3 teams that can compete with Bayern Munich and hopefully the championship will be won by a team other than Bayern soon. Like everyone else, I want it to be a competitive league.
Yes it was dominating for a long time but recently since past few years, Bayern haven't been upto mark due to which other clubs have found a way to get close to Bayern on the table. I think over th e next few years it will become more competitive as Bundesliga does have some crazy underdogs and if they find a way to be consistent then they can really become one to put the eyes on for title race. Everyone wants a competitive league and I think it is becoming slowly and I think it will become harder by harder as the season goes by.
