ESPN wrote an article about Manchester United's transfer operations in recent years, and said that Manchester United often has to pay "Manchester United tax" when purchasing players.

The article talks about Hoylen's transfer: Hoylen's initial valuation was about £40 million, but after the first round of difficult negotiations, Manchester United told Atlanta that it would not pay more than £60 million in transfer fees for players. But in the end, Manchester United bought the striker for more than £70 million, a figure far exceeding the value of the player itself.

And last summer, Manchester United changed their signing strategy and gave up Branswitter's transfer because United believed Everton was too expensive for the players.
