The £30 million acquisition of Andriy Shevchenko was Roman Abramovich's first costly executive signing.
It was a decision that overrode José Mourinho's misgivings about what Shevchenko could offer to the Blues.
Mourinho humiliated Abramovich's record signing by not naming Shevchenko as one of the untouchables and not giving the former AC Milan forward a reason for not playing.
José used Shevchenko as a scapegoat to make a clear point to Roman: "I'm the manager, I make the signings."
Abramovich's view was that: "It's my money, I own the team, I'm the boss, so I call the shots."
Duncan Castles at The Guardian documented Roman's attempts to force the Special One to start Shevchenko:
Abramovich's close friendship with his £30m summer signing appears set to cost Chelsea the services of the man who has won back-to-back titles in his two full seasons in England.
The Russian and his advisers told Mourinho in a recent strategy meeting that under no circumstances would he be allowed to add a striker to the squad and instructed him to use Shevchenko properly.
An earlier attempt by the manager to swap Shaun Wright-Phillips plus cash for Jermain Defoe had been put to Tottenham only to be vetoed by the Chelsea hierarchy.
A subsequent loan exchange of the England winger for Aston Villa's striker Milan BaroŠ was also blocked, even though no expenditure would have been involved.
With Fernando Torres, it's déjà vu all over again.
Abramovich filled Shevchenko's void with £50 million for Torres, in the process breaking the club and the British transfer fee record.
Deep down in Roman's mind, he knows he grossly overpaid for Shevchenko and Torres.
The Ukrainian was a significant factor in the Special One's exit, which cost the Blues owner an additional £18 million in compensation.
What do Carlo Ancelotti, André Villas Boas and Roberto Di Matteo have in common? All three didn't rate Torres and all three were sacked by Abramovich.
Rafa Benítez is the first Chelsea manager that believes in Torres and will bend over backwards for El Niño.
The hiring of Benítez, who used to trash the Blues, is Abramovich's last desperate attempt to get Torres scoring like a £50 million-valued forward.
Signing Falcao would mean Abramovich giving up on Torres, who was signed to appease the feeling of emptiness after the Shevchenko fiasco.
This quote from Mourinho gives you an idea why Roman may persist with Torres, even though Falcao is just on another level (from Sport via John Cross at Mirror Football):
I think that he [Abramovich] sometimes thinks too much with his heart and helps people in football that he likes instead of thinking about getting the best for the job.
