Fiorentina coach Delio Rossi admits his players fear their own fans.
The jeers again rang out during home defeat to Chievo Verona yesterday.
"Playing at home when your players are frightened really does not help, as it robs them of energy and focus," said Rossi.
"We play well away from home and still do not pick up the results that we deserve. It's difficult to do well when there is fear and we need calm, which at the moment is just not here.
"Everyone has to push in the same direction. The common good must come above personal interests."
