It's only been a bit more than a month since the summer transfer window has closed but that doesn't seem to matter for several European clubs. With their sights set on what may happen at the end of the season, Borussia Dortmund are already looking forward to securing Erling Haaland beyond 2022.

The Norwegian superstar is one of the most coveted strikers on the planet right now and, even though the Bundesliga side has been able to fend off interest from the likes of Real Madrid so far, it faces a serious threat for next summer.

By the end of the 2021-22 campaign, a €75 million release clause would active in Haaland's contract. Needless to say, countless continental rivals will approach him when that happens and that's why the German club wants to offer him a new deal, improving his current €8m salary and probably increasing his release clause as well.

Dortmund reportedly ready to propose huge salary raise to coveted striker Erling Haaland

Ever since he rose to stardom in Borussia Dortmund, Haaland has been the subject of multiple transfer rumors with PSG, Bayern, Barcelona, Manchester United, and Chelsea frequently linked to the Norway international.

Arguably the most fascinating striker in world soccer with a bright future ahead of him, Erling Haaland's stock has significantly risen but his current contract could make him available for a bargain €75m next summer.

That's why Borussia Dortmund will try to do everything they can to avoid losing him for such a low price. According to Bild, the club will propose Erling Haaland a new contract worth €15 million per season, almost double his current salary.

While that new deal will try to satisfy and seduce the 21-year-old to stay it would also intend to include a much higher release clause to procect him from any other clubs. If Dortmund ultimately propose this contract extension, the ball will be in Haaland's court. And in case they have to say goodbye to their fantastic No. 9, they might have a number of alternatives in mind.
