Sheikh Jassim might have to observe his switch spending if he buys United regardless of his unimaginable wealth, in keeping with soccer finance knowledgeable Kieran Maguire.

The Red Devils are believed to be chasing an £85m transfer for France striker Randal Kolo Muani, per Fabrizio Romano, however Maguire has warned that such costly offers would danger breaching UEFA's monetary rules.

"For UEFA, it’s slightly more complex," he advised Football Insider when quizzed on how United may get across the strict guidelines.

"They have recently changed to their new financial sustainability regulations which allow clubs to only lose £51m over a three-year period.

"Also, we’re successfully transferring to a wage cap of 70 per cent of revenues, though admittedly this has not been a problem for United in recent times."
