Prior to the 2013-14 Premier League season, the Short Term Cost Control (STCC) rules were agreed upon for the next three years, and then renewed in 2016 with the purpose of stopping salaries increasing in line with the new broadcasting revenues. The STCC rules state that, "Clubs cannot increase their player wage bills by more than Â£7m compared to the previous year unless they can demonstrate that any excess is due to individual club revenue sources."
This means that Everton cannot go and buy Â£100m worth of players and renew the contracts of many of their young stars because the wages would rise by far more than the Â£7m growth that is permitted. Even though Everton now has the funds necessary through the takeover to buy expensive players, they may not be allowed to. Unfortunately, Everton cannot do what Manchester City did in 2008 after they were taken over by Sheikh Mansour with the massive Â£32.5m signing of Robinho from Real Madrid because it would not follow the STCC rules.
