Maybe Dortmund don't have a squad as strong as Bayern Munich but they are still able to maintain their level in the Bundesliga. I really like their mentality for years. They have been making a lot of profit in talented player sales and they still manage to stand still in the league despite losing strength.
For example they haven't filled Bellingham's space with a similar talent. His contribution to the team was really significant you know. However they still don't make it a problem for themselves. We are watching them only two points away from the leader and having a winning streak of four games now.
Their mentality was put to dust in the last game of last season when in front of their home fans they needed to win at all cost to win the Bundesliga and they couldn't against a weaker team like Mainz,they drew 2-2 in that game,where was this strong winning mentality when it was the most needed,nowhere to be found.
They have a good streak it is true but I don't think they are the real contenders this time around,we have Leverkussen this season in a much better position and a much better squad that is keeping the same points as Bayern and they even got a draw at Bayern,they are the most serious contender for the title during this year.
