Billionaire Russian owner Roman Abramovich has hit the financial brake at Chelsea, chief scout Frank Arnesen said on Saturday.
"The (worldwide) financial crunch has meant Roman has hit the financial brake and asked us to cut deep," Arnesen told the Guardian newspaper.
"We have cut down significantly on scouts and other activities. However, we are now getting close to the time when the club can carry on without Roman's money," added the Dane who is also Chelsea's director of youth development.
Abramovich has poured in hundreds of millions of pounds since buying the Premier League club in 2003.
Chelsea will attempt to consolidate their position at the top of the Premier League table when they visit Blackburn Rovers on Sunday.
