Flood believes good housekeeping and a harmonious dressing room are vital tools to have if you are to be successful.
Flood used Newcastle as an example of how things can go seriously wrong on and off the pitch.
Now in the Championship, Mike Ashley has put the club up for sale for £100million.
Flood said: "When you see clubs falling apart, Newcastle for example, most people would lay the blame at Mike Ashley's door.
"He has probably mis-managed the club in a sense and that has drifted down to the players. There is a lot of disharmony there.
"It is about getting the belief and the stability at the top, getting a positive way of thinking, getting people who surround the players and make them feel good about being there.
"The players feel happy to be at this club. The lads deserve the chance to show what they can do in the Premier League."
