That is just patently untrue. It has been reported over the years that Joel is signing off on most incoming and outgoing transfer, amongst other things. He vetoed Martial's exit years ago, for example. I believe it was because he thought Martial is going to become Manchester United's Pele. God in heaven. Anyway, he is absolutely involved in the operations of the club. Richard Arnold, and his predecessor, have had to run most moves by him first. And what I told you was proven correct mere hours later.
If Ratcliffe didn't want to sit in a corner, he should have paid more. It is delusional to believe Joel and Avram will let him do as he pleases for a mere 25%. That's just not how it works. This would probably be the first enterprise in the world where a minority shareholder is calling the shots in any way. And you cannot separate football operations from financial operations in any meaningful way. Ratcliffe can appoint who he wants, but his appointees need money to do their jobs. And the ones holding the money are the owners of the club. What happens when Ratcliffe's Director-of-Football says he wants to sign Joe Schmoe for 80 million but Joel says "No", because that's too much or Joe's wage demands are too high? So, unless "football control" means Ratcliffe is going to come up with a new formation, coach the players, and prepare nutritional plans, it all remains window dressing when he doesn't control the funds. Well, unless he has decided to continue pumping hundreds of millions into the club each summer.
