I followed and watched Haller nearly a year now and its the same for him as with Haaland , he also has unique playing style.
If you looking at the statistics he is at some points already a bit better as Haaland .
I guess we will see a very much diffrent and better Dortmund as we have seen last season.
Will take your word then since you have seen him play. Glad that he has improved since he left West Ham for Ajax and now Dortmund. It's a new chapter and new challenge to prove himself that he is capable of playing first team striker for a good team at big competitions. Hope that he can do much more that what Dortmund expects of him.
So what do you think- will they be able to give Bayern a better and tough competition for the title than last season?
I was positive about Borussia Dortmund in last few days as they were investing and having few exciting players for next season but now with the words from @Lafu I have feeling that now we can watch very tough challenge between these two giants from Germany in coming season because they had never been serious about trophies but now after selling Haaland they have few good signings which can improve their strength, and they can fight for title.
In last season they were in good position but suddenly have few big setbacks and specially early knocked out from Champions League were also had big impact on player's mentality but with their preparation going for next season look like they will be in better position and could be more lethal than past.
