Premier League clubs could offer an app to fans which would send virtual cheers or jeers from their homes to stadiums in under a second, in an attempt to generate an atmosphere for matches behind closed doors.
Sportsmail has learned that Liverpool, Manchester City and Arsenal have held talks this week with a German technology company who have developed an app which will offer supporters four choices for generating noise to be played in empty grounds.
The app also gives clubs the option of using different sound levels for home and away supporters, which could reduce some of the objections to the Premier League campaign being concluded at neutral venues by maintaining a semblance of home advantage.
