Bundesliga will definitely be more interesting if other teams strengthen their players, and probably compete with Bayern Munich for the title. Premier League remain one of the best League in football because their is high level of competition within the teams. Which made it quite difficult to predict who will win the League. But, Bayern Munich have won the Bundesliga title for 10 consecutive seasons, and will also win next season if no team is well prepared to compete seriously with them.
Every seasons Bundesliga teams will always be attempts to strengthen their squad by buying new players and the latest teams who very agressive in transfer window is Dortmund that so far they get 8 players and i think this is prove that Dortmund serious want to compete with Bayern Munich for race title but indeed the most problem is while Bayern able to get star players but other teams only able to buy mediocre players this because financial strength for Bayern is very strong so that's why they can get the players they want and if these gap of financial strength cannot be reduced then it is difficult to other teams compete with Bayern
