Are you able to start off a new season with 100 million pound transfer fund with any club

there are several ways to have a perfect season.
Option 1. One day before each match take control of other team make them lose
Option 2. Have a massive squad cheepist way to add players is football management data editor section located ( my p.c. -> c drive -> program files -> sports interactive -> Football Manager 2008 then load data editor.)
Option 3. Take control of your team then take control of team with lots of money
Then make them by a rubbish player of all there money (spend this money on players )

Lats Option. Take control of the team you wanna by the players from and you can get them for $0 this might reduce the market value of certain players. All the best of luck
