Pubs in Cardiff and Swansea suspected of showing Premier League football matches illegally using foreign satellites face prosecution, BBC Wales has learned.
In the last four months the Premier League's private investigation firm has visited nearly 200 pubs in south Wales.
The League is planning to bring up to 100 prosecutions across Wales and England this season.
The first will be against The Rhyddings Hotel in Brynmill, Swansea, shortly.
