Sebastian Haller is a talented player. He has done very well in the Eredivisie League. But he did not play well in the Premier League with West Ham. There is a lot of competition in the Premier League. But I think he will play great for two years in Bundesliga with Dortmund. Then again, any Premier League team will buy Sebastian Haller at a high price. In a few years, we will see Sebastian Haller again in the Premier League.
In this case, I still feel that the EPL is not very suitable for him because if we look at it from a performance perspective, it is clear that his performance was much better in Frankfurt, but in the EPL he lost his form but regained his performance at Ajax.
Now he's back in the Bundesliga hoping for something good. I hope he doesn't fade in terms of performance again.
