Chelsea owner Roman Abramovich is planning a £100 million summer spending spree.
The Sun says the Blues owner met his coach Carlo Ancelotti at the club's Cobham training ground yesterday to discuss plans for buying new players.
There will also be a clear-out of 'dead wood' from the squad and a thorough review of the coaching staff and academy structure.
A senior Chelsea source said: "Carlo has the full backing of Roman and that will mean the kind of money being spent this summer that we haven't seen since Mourinho was in charge.
"Roman believes Carlo is the right man and will give him exactly what he needs to rebuild the team.
"This squad has gone a bit stale and needs to have some fresh blood."
