The club has taken time off from sacking managers and signing duds to launch legal action against SEGA and Sports Interactive, the makers of the Football Manager series, because the game includes the club's name, and does not include the club's logo. The logo has instead been replaced by "a simplified red and white striped" design.
In their action, United claims this deprives the registered proprietor of its right to have the club crest licensed.
Sega and Sports Interactive have responded by saying that the club has been used in an identical manner since the release of the first Championship Manager game in 1992, during which time there have been no complaints from United.
At a remote hearing on Friday, United's barrister Simon Malynicz QC asked Mr Justice Morgan to allow the club to amend its claim against Sega and SI to include allegations involving "the practice of supplying "patches" or 'mods, ' essentially downloadable files containing replica trademarks, which consumers then incorporate into the game".
Both Sega and Sports Interactive maintain that they have done nothing wrong in using the club's name, believing that blocking them from doing so "would amount to an unreasonable restraint on the right to freedom of expression".
On behalf of Sega and SI, Roger Wyand QC argued, "The claimant has acquiesced in the use by the defendants of the name of the Manchester United football team in the Football Manager game and can not now complain of such use".
Wyand also explained that copies of the game had been sent to a number of United officials and players for several years, and that "there have been a number of positive press comments and tweets about the game by them".
In the written defence to United's claim, Wyand added: 'Further, the claimant's staff working in the data analytics and scouting teams have contacted SI on various occasions asking for access to the Football Manager database for scouting and research purposes'.
The judge chose to reserve his judgment on United's application to amend its claim to a later date.
