Yes, this is what I said a few days ago and we know Dortmund is a team with profitable business prospects so it is not surprising if they release important players and look for players at lower prices because the title is not their main target.
Dortmund is actually quite good at honing the abilities of the players so that the players can become potential players but they actually make it a business so that the players can be sold for high prices to top clubs without considering their strength, but even though they sell star players they can still stabilize their performance and not experience a drastic decline, and now they have managed to buy a great striker at a low price, most likely Dortmund will hone Guraissy even stronger than last season and will sell him to a club that is willing to buy him, but top European clubs seem to need to think long and hard to recruit this player considering his age is 28 years old, Saudi Arabian clubs can be a good choice for Dortmund the club will receive a big profit.
