Abramovich often interfered at Chelsea yet they won lots of shiny tings because they signed good players and appointed good managers. An interfering owner doesn't always mean a poorly ran club - if the Chairman/DOF are any good then they stand firm and make the owner take more of a backseat.
Kenwright did the opposite & Brands decided to replace prine Gana with Gbamin & Delph and signed a lazy/uninterested player like Moise Kean when we needed an experienced CF to mentor a young DCL then moans to the media that the owner sacked Silva against his wishes when we were in the bottom 3 in Dec thanks to his pap summer business.
