​Borussia Dortmund CEO Hans-Joachim Watzke has revealed the reason for the club signing Erling Braut Haaland from Red Bull Salzburg. The Norwegian was signed in the January transfer window after he had a wonderful first half of the season in Austria.

He has continued his great form with Dortmund as well, netting nine goals in his first six matches for the club. Meanwhile, speaking about his signing, Dortmund CEO Watzke has revealed that the idea of the club was to sign a striker who had a unique way of playing.

“We always wanted to have a centre forward who has a different way of playing football,” Watzke told Goal.

He then went on to reveal that they were looking for a tall striker – a classic number 9 – and that Haaland was the perfect candidate for their requirements since there wasn’t another striker like him in the market.

“It wasn't about a second striker, but a tall, physically strong classic number nine. But this guy also had to come onto the market first. There are not many who are 1.94 meters tall and that fast. Actually, nobody else comes to mind. It was just an opportunity that you don't get very often.

He also added that they had been following him since December.

“I've been following his progress a little longer. I first met him in December. I think we both quickly felt that it could be something."
