Select "Game Options" then choose "Add Manager". Enter a name, etc. and pick either a club in the Premier League with lots of transfer funds or an opposing team just before you play them. At the team selection menu, randomly allocate positions and put a player such as a forward in goal. Then go to "Tactics" in the bottom left and move all their players to the edge of the pitch, leaving a big gap for your players to waltz through and score easy goals. After winning the match, click the manager's name and select "Retire". Then, take control of your old team again.
