While Im not sure about PSG , you did have Bartomeu actually saying this when asked about Arthur
The radio station El m?n a RAC 1 confronted Bar?a president Josep Maria Bartomeu with the numbers on Tuesday. Asked whether Arthur, who the club paid €30 million in 2018, was truly worth €80 million, Bartomeu pointed at his Transfermarkt value.
"It is supply and demand, that is how it works," Bartomeu said. "Arthur is the sort of player that is valued in the world of football. Until a few months ago his Transfermarkt value was €70 million, then his value sunk because of the pandemic. But until March he was worth €70 million, so we are not that far away from the evaluation that he had in March."
You never know with Bartomeu.
