Hardly anyone should have been surprised when Borussia Dortmund and Manchester City announced on Tuesday afternoon what had been apparent for many weeks.

"The player Erling Haaland is about to change from Borussia Dortmund GmbH & Co. KGaA to Manchester City Football Club Limited," announced BVB, which is listed on the stock exchange, in an ad hoc announcement.

At this moment, many Dortmunders will have felt a feeling of relief rather than the pain of saying goodbye, because the case had become an exhausting noise in the everyday life of the Bundesliga team over the past few months.

Now there is finally clarity, and some fans will even cheer a little bit.

Because almost at the same time as the Haaland message, Dortmund announced that Karim Adeyemi from RB Salzburg would step up the attack.

"After the transfers of Niklas Süle and Nico Schlotterbeck, we've got another very exciting player in Karim Adeyemi," said Sebastian Kehl, who will be promoted to Dortmund's sporting director in a few weeks.

Kehl finds Adeyemi's "speed and goal threat impressive", the German national player is "already very advanced in football and athletics at just 20 years of age" and has "enormous development potential", explained the future head of sport.

He has also been a fan of Borussia Dortmund since childhood.

"As a little boy, I was fascinated by black and yellow fast-paced football," explained Adeyemi, "so I quickly realized that I would like to switch to BVB."

Total volume of up to 300 million euros

Something like that must sound much more likeable to everyone in Dortmund than the constant debates about crazy sums of millions that accompanied Haaland during his rather disappointing second half of the season.

Although it was stated in the ad hoc announcement about the change of the Norwegian superstar that "the contractual details (...) still have to be agreed and documented", the general framework has long been negotiated.

The sports medical examinations, which are part of such a deal worth millions, have already been carried out.

Haaland was released from training on Monday to be checked by his future employer in Brussels.

What sounds like a mere formality could actually have been a bit more difficult in this case, as Haaland came to Dortmund with a reputation for being a rather injury-prone player.

After a year and a half without any major problems, he was actually unable to play again and again in the season that is now coming to an end due to various muscle problems.

Here lies the risk that Manchester City is taking with the deal, which is said to have a total volume of up to 300 million euros.

The fixed transfer fee is 75 million euros, according to media reports, Haaland receives a salary of 30 million euros per season for his five-year contract, plus double-digit millions for Erling's father Alf-Inge Haaland and for the agency of the consultant Mino Raiola, who died a week and a half ago.

Dortmund team is more homogeneous

It is not known whether the agent's death had any impact on the business, but it is clear that BVB now has the money for the attacker's successor.

For Adeyemi, who should cost around 30 million euros, but who, unlike Haaland, is not a classic penalty area striker.

And probably also for another top scorer, who should correspond more to the profile of a classic number nine.

There is speculation about Sebastien Haller from Ajax Amsterdam, with whom Dortmund is said to be intensively involved.

Bayer Leverkusen's Patrik Schick is unlikely to come after the Rhinelanders qualified for the Champions League, but Czech talent Adam Hlozek from Sparta Prague and Stuttgart's Sasa Kalajdzic are among the candidates.

What is relatively clear is that none of these players will be able to match Haaland's incredible 85 goals in 88 games.

But coach Rose can hope to find better conditions in the future to develop a homogeneous team with real team spirit.

Haaland was not unpopular, but he always had a special position and is now switching to nothing but world stars at a club that his father has been playing for.

However, in a completely different era, when Manchester City was not yet a top club endowed with huge sums of money from the Middle East, but rather one of those crisis-prone traditional clubs, of which there are so many, not only in England.

Experts now have plenty of material to discuss the question of whether the coach Pep Guardiola, who loves midfielders and who has had no problem doing without strikers in the past, can turn the highly talented Haaland into a world star.

And Dortmund can ponder why their completely renewed team can finally give them a German championship again.
