Dortmund got Serhou Guirassy with clause of 17,5 million Euros and this was Dortmund success in this summer transfer window because it can also be seen that Guirassy is player who is being targeted by several other big team thanks to his greatness.
Even though I quite regretful about Guirassy departure to Dortmund because he could have been sold at any time if it was profitable and the chances of winning the title were quite remote, but everything has happened and this is the decision that Guirassy took.
He will be the same as Kane with Bayern Munich where both were the best goal machines for the team that had them, but had no chance of winning the title in the previous season.
I have the thought that Stuttgart have actually made a good offer to Guirassy but he rejected the offer because I know that Guirassy has a big desire to join Dortmund so he can have a bigger career and we all know why this player chose Dortmund because this club is like a bridge for him reliable players to have a bright future like Haaland and Jude Bellingham.
