Sky customers have the chance to get a year’s subscription to BT Sport for half price until midnight on Friday.
The deal reduces the usual £27.99 monthly fee to £13.99 a month.
Subscribing to the deal allows customers to watch 52 Premier League and FA Cup games live, but perhaps more importantly it will allow subscribers to watch every Champions League match. English clubs Manchester United, Manchester City, Liverpool and Tottenham Hotspur will compete in this season’s tournament.
The offer, available on www.livesocial.co.uk/bt-sport also gives access to all BT Sport channels, as well as ESPN and Box Nation.
The Champions League group stages begin on September 18 and 19, with the draw for the stage due to take place in Monaco on August 30.
