Chelsea owner Roman Abramovich is demanding answers after a disappointing summer market.
The Daily Express says Chelsea were left stung by three high-profile snubs.
Romelu Lukaku rejected a return to Stamford Bridge to link up with Jose Mourinho again at Manchester United.
A fee was agreed with Arsenal for Alex Oxlade-Chamberlain but he decided to join Liverpool.
While Everton midfielder Ross Barkley pulled out of a switch on deadline day.
And Abramovich wants to know what went wrong.
Manager Antonio Conte is also fuming. He has a limited role in the club's transfer policy and wants explanations for the failure to sign key targets.
