United made just three summer signings in Harry Maguire, Aaron Wan-Bissaka and Daniel James and have already found themselves short up front early in the campaign after letting Romelu Lukaku and Alexis Sanchez leave for Inter Milan.
Premier League leaders Liverpool already enjoy a 10-point lead over United, who sit in eighth, just six games into the new campaign. However, United still remain out in front of their Premier League rivals when it comes to making money.
City's revenue for the 2017/18 season was £500.5 million, while Liverpool's income for the same season was £455 million. United's net profit in the 12 months to June 30 was £18.9 million as their wage bill again increased by 12 percent to £332 million.
