Fjortoft is close to the Manchester City striker.
He wrote for the Daily Mail, "There was Ole Gunnar Solskjaer's famous private jet flight from Manchester to Salzburg to talk him into joining Manchester United. You wonder what might have happened if Ole had managed to persuade him? But football is full of what ifs! It wasn't as if he turned down Ole and United. As Team Haaland said, he chose Dortmund.
"If you move to Manchester United, that is an end-game transfer. You don't do two years there and move on elsewhere. It's a move for the best years of your career. And it wasn't time for that move. Dortmund had the reputation for developing young players in Lewandowski, Mario Gotze and Pierre-Emerick Aubameyang. They offered the chance to develop outside the bubble of the Premier League.
"Dortmund was just big enough to test himself. They had huge crowds and the Yellow Wall, which would have been an attraction. But despite how good they are, Dortmund is still a relatively small city, a little bit off the beaten track."
