The most enticing match from a marketing point of view would see United face Cristiano Ronaldo's Al-Nassr. Ronaldo left United to join the Saudi giants in acrimonious circumstances in 2022 following his tell-all interview with Piers Morgan, in which he slammed the way the club had been run and hit out at coaches Erik ten Hag and Ralf Rangnick.
The prospect of Ronaldo facing his former club in Riyadh would be a huge draw for fans and broadcasters and would likely be supported by Bin Salman, who is keen to draw tourists to the Kingdom.
While United have plenty of free weeks due to their lack of European football and being knocked out of the Carabao Cup, Al-Nassr have a busier schedule, competing in four separate competitions.
