Even if I had one today, it probably wouldn't work tomorrow. Sky is ruthless about pirated streams. They don't last long.
As others said you won't find anything free that will work for more than couple of hours. I would recommend you to ask for a trial for the paid service offered by /u/Ace-iptv
It is possible to get most of the content for free but it definitely ain't worth the effort. You will have to do it over and over again.
In term of quality and time effort you're better of, by watching online streams from those thousands of livestreams homepages
Realistically any playlist that provides decent streams of Sky and sports tends to disappear pretty quickly. You would be better off considering a paid service, a good selection are listed in the spreadsheet of the sticky post - https://www.reddit.com/r/IPTV/comments/560nyo/collaboration_list_of_iptv_providers_their/
