Those conversations will continue on Thursday when the Premier League meets again to discuss wide-ranging issues including a restart date, television scheduling and contingency plans if the season has to be curtailed.
Premier League clubs have unanimously voted to resume contact training as "Project Restart" moves to phase two.
Nuno Espirito Santo's side and Dean Smith's charges are now allowed to "engage in tackling while minimising any unnecessary close contact" at Compton and Bodymoor Heath respectively.
The Premier League said it would not reveal specific details regarding clubs or individuals who had returned positive findings. "Discussions are ongoing as work continues towards resuming the season, when conditions allow".
The decision to return to contact training was agreed following consultation with clubs, players, managers, the Professional Football Association (PFA), the League Managers Association (LMA) and the government.
