A Nkunku-Garnacho quasi-swap swap deal would, for example, generate more than enough short-term PSR leeway for United not to have to increase prices for fans mid-season. If the clubs are tapering their spending and increasing the burden on match-going fans because of cash flow, that is a separate matter. And for United, cash flow is real concern.

Manchester United are 'open' to signing a new striker this January window and have been linked with Chelsea's Christopher Nkunku.
