There are fears that as many as 50 players could dent Premier League's Project Restart plan by refusing to return to action due to concerns over their safety.
The Mirror report that one club executive feels there could 'one or two' players from every club that decides against returning to complete the 2019-20 season.
Manchester City striker Sergio Aguero is among the players to have gone public with his concerns but others, such as West Ham's Manuel Lanzini - who believes action should not resume until a vaccine is available - have also spoken out but neither have said they would snub any return.
