With Haaland's price being so high I also doubt any club can afford to pay in the current financial crisis situation. Indeed, my prediction is
the possibility that Haaland will stay at Dortmund at least for one season. Who knows in the next season the pandemic is over and the finances of big clubs are back to normal again, so Dortmund can sell Haaland at a good price.
When big clubs fall in love with one player, and if they have huge budget from corporations like PSG or Manchester City, they can make surprising big transfers. I agree the financial crisis will make them to think more carefully, think twice but it won't restrict their ability to do big transfers.
Haaland is a young player and he has a long career ahead. He is worth for big transfer.
Regarding Jadon Sancho, whose appearance has decreased significantly compared to the previous season
Sancho is a reminder for Haaland too. Young player need to keep up top level performance for continuous seasons. They must be able to do so in order to reach the levels of Messi and Ronaldo. Haazard, Neymar, Bale have never touched the levels of Messi and Ronaldo because of their unstable performances.
it seems like Manchester United are no longer interested in buying him, even though the price has decreased considerably. Because according to the Manchester United legend,
Lee Sharpe suggested that Man United buy Jack Grealish, who has performed much better this season than Sancho. And it's possible that
Grealish's price won't be as expensive as Sancho.
Sancho is younger than Grealish. Transfer cost need to be combined with age of player and their potential contributions in future.
