Everton boss Roberto Martinez has enjoyed his first six months working with chairman Bill Kenwright.
Martinez considers himself fortunate to have worked with the likes of Huw Jenkins (Swansea) and Dave Whelan (Wigan) prior to being picked by Kenwright in the summer to succeed David Moyes.
"One of the problems of the modern game is that the chairmen and owners are normally business people who have no links or connection with the club," Martinez told the Daily Express. "That becomes a problem because your decisions are going to be based on finances.
"I have always been very aware that for a manager the relationship with his chairman is unique because you need to have that stability. Bill Kenwright, Dave Whelan and even Huw Jenkins at Swansea - all three - are mad fans of the football club and then, on top of that, they are people with great vision.
"I don't think people from the outside realise how influential Bill has been over the years because he has had to make very tough calls, but always for the good of the club. That is something we are losing in the modern game.
"That is a real shame because you don't want to see what is happening at Portsmouth, or even Hull previously.
"But when you are in the hands of an investor, rather than a football man with the right thoughts, you are risking a lot. Not just the history of over 100 years, but the memories of thousands of fans who have been growing up with that football club in their community."
