Everton players are upset with the tough training regime for manager Marco Silva.
The Sun says the Goodison men have had a slow start to the campaign with the Portuguese coach.
And following their humbling at home by West Ham last week, discontent among the squad has increased.
Many of the players, headed by seniors, believe that TOO MUCH work is being done on preparation, including sessions that are above their heads.
One source claimed it was similar to problems during the reigns of Roberto Martinez and Ronald Koeman, who overloaded the players with too much information.
The squad have got together and are dropping hints with the management that they should be doing fewer hours and that the tactics should be simpler.
