Eidos decided not to all SI to renew the rights to the brand, as they wanted a bigger cut - so they employed a new team to create a brand new game.
All Eidos owned from the deal was the "look and feel" of the GUI. SI owned the game engine and the player database.
SI then went out and purchased the rights to Football Manager from Kevin Toms, who wrote the original spectrum version.
