Premier League clubs must reassure players there will be no repercussions if they are unwilling to risk their health by returning to action during the COVID-19 pandemic, former England manager Sam Allardyce has said.

Several players have expressed concerns about the league's plans to resume amid the novel coronavirus outbreak, which has infected more than 4.6 million people globally, causing over 310,200 deaths.

"Getting the players fit in four weeks could be done, but that's the least of their worries. I think the biggest challenge for players will be dealing with the mental side," Allardyce wrote in a column for The Times.
