I'm shocked that Borussia Dortmund has not offered Mats Hummels a new contract, even though it is a one-year contract. Mats Hummels delivered a good performance against Real Madrid in the UEFA Champions League finals. Because of Mats Hummels, Real Madrid could not score so many goals against Borussia Dortmund. From what Mats Hummels displayed against Real Madrid, he still has a lot of things to offer as a defender. If it is certain that Borussia Dortmund wants to part ways with Mats Hummels this season, he will get a new contract with another club since he is on a free transfer.
The Borussia Dortmund team is indeed moving beyond most people's reasoning because from the sale of their best players alone it can be seen that the Borussia Dortmund team really values money more than long-term player contracts. Because after they are able to make players better, they will always look at markets that are more suitable for those players in order to earn more money, so I personally no longer feel surprised by Borussia Dortmund's attitude towards all their players.
