When Manchester United sold Daniel James to Leeds for £25million last summer it was just the fifth time in a decade they had managed to make a profit on a player they were ready to discard.
United got lucky with James. Marcelo Bielsa was obsessed with the winger and he'd done just about enough at Old Trafford to suggest there was still potential there. If Leeds were selling him now they wouldn't get £25million for him.
James was the first of the 2019 intake out of the door but he will be followed by Aaron Wan-Bissaka this summer. United will do well to avoid making more than a 50% loss on the £45million that Crystal Palace managed to hoodwink out of them for the right-back.
