The critics are back following the Three Lions' dismal showing in Saturday's 2-2 draw with Switzerland at Wembley in tournament qualifying and Keown believes that the Italian tactician needs to open his mind to what the players want if he wants to succeed.
"It is about whether he has learned when it comes to playing tournament football," said Keown.
"He has to meet the needs of the players and support them in a better way.
"English players are very social. Italians are a bit more robotic - they spend more time in their rooms, they go to bed earlier, they don't eat between meals.
"We have become much more professional with our diets. They are subtle changes you can introduce to meet the players halfway and make them feel more comfortable and happy.
"We can't have a situation where players are dreading being there. We want them to love every moment of being at a tournament."
