The Norwegian starlet did not waste the opportunity to think about his future when signing with the black and yellow club.

Erling Braut Haaland surprised almost everyone in the world of football by choosing to join Borussia Dortmund during the ongoing transfer window. Well, the player did not stop there and thought about his future when he signed his deal with Lucien Favre's side.

According to a report by Sport Bild, the Norwegian starlet does not seem to be interested in staying with the yellow and black side for long, which urged him to include a secret clause in his four-year deal with the German outlet.

That clause, according to Sport Bild, would see Haaland forcing Dortmund to sell him if a bigger club comes knocking on his door with a better deal. This clause can only be exercised after his second year in Germany, which means that Haaland could be free to leave Dortmund in 2022.

This is not an uncommon clause for Borussia Dortmund players to use. Back in the day, Mario Götze used a similar clause to force his departure from the yellow and black side to join Bayern München. Even so, Borussia Dortmund fans should enjoy Haaland's performances with the team while they last, since the player does not seen interested to stay for a very long time in the Bundesliga.
