Question/Instruction: How has Roman Abramovich's ownership impacted the success of Chelsea FC over the years?

Given material: CHELSEA owner Roman Abramovich has loaned the club a monster £1bn.
That's according to the financial reports of the company through which the Russian owns the club.
Fordstam confirmed that the interest-free loan has surpassed the £1bn mark of the first time.
The figure has risen from £984m the year before to an eye-watering £1,041,243,000 up to last June.
Within the terms of the loan Abramovich has the right to demand that the money is paid back within 18 months, however that situation is extremely unlikely to arise. For the time being at least.
In the financial report, Fordstam’s Paul Heagren reported: "The company has received confirmation from the ultimate controlling party that sufficient funds will be provided to finance the business for the foreseeable future."
Abramovich bought the club in 2003 and bankrolled an unprecedented period of success for the club.
With Jose Mourinho back as manager for a second time, Chelsea have got their hands back on the Premier League trophy for the first time in five years.
