Football Manager 2023

Load up the challenges on the right side of the main screen. Pick The Invincibles challenge on easy. Pick Manchester City, if it doesn't let you pick them directly, like for me, then pick random until it lands on them. Start the game and before every match, quick save. Use auto pick for the strongest squad and sim the match. If you lose, quit to the main menu and load the game. It is six matches as the season "starts" for match day 33 from 38. Should be doable in 10 minutes. It is quicker if you ignore all news and skip through everything. It does not unlock until after the season and about a week into the next season.

Select ‘The Saviour Cometh’ challenge. Choose English Premier League Division. Choose Manchester City (or another top team like Liverpool). I chose City because of, well, Haaland and squad depth (injuries happened a lot). Start your save up. Simulate games via instant replay. Keep an eye on results (just in case). Load games if that’s not the case and things look risky. You should be able secure relegation survival before the season ends. Took me <30 mins max.
