BT Sport is introducing a new Red Button service, running alongside its two existing linear channels.

Launching on September 19, BT Sport Extra will initially screen coverage from the French, Portuguese and German football leagues.

Access to the channel will vary between providers. Sky subscribers will need to press the Red Button while on a BT Sport channel, while BT TV customers need to switch to channel 527. Virgin Media customers will need to wait a few more weeks, while those customers receiving BT Sport over the air will miss out altogether.
