I don't think Bill is looking to sell his shares. I think he would if the right offer came along, but that offer won't come along unless someone is truly determined to buy Everton FC, not just any football club. I think Bill's dream is to own a successful Everton.
I think he has put his faith in the wrong people at the club, as well as made some poor choices (such as allowing the Kitbag deal to go through) in his quest to get Everton a new stadium without being able to fund it himself.
I do not necessarily believe the Kenwright must leave for Everton to succeed, but something does have to change. The club needs a shakeup in regards to the commercial side and needs to present itself as one of the top clubs in the world. I think Martinez is a good manager to lead that revolution on the pitch, but we need an equal visionary in the boardroom to carry that to fruition.
My opinion is less Kenwright out and more Elstone out. Elstone has failed to grow the business as well as one would expect with the explosive growth of the Premier League, and I do think that a good or great CEO would see Everton in a much more positive position moving forward.
Obviously, this is all speculation, but I find it both odd and concerning that our turnover is so much less than teams like Spurs and Newcastle.
