Premier League clubs are considering increasing their Covid-19 testing programme amid concerns that the weekly screening introduced at the start of the season is not fit for purpose.
Sportsmail has learned that returning to the twice-weekly testing used during Project Restart has been discussed informally by clubs due to fears that a seven-day gap between tests could lead to the virus spreading within their bubble without intervention.
The Premier League have an open mind on the issue. On Tuesday, they signalled their commitment to thorough testing by agreeing to cover costs for EFL clubs whenever they are drawn against top-flight opposition in the Carabao Cup and FA Cup this season.
