Has anyone got any direct experience with the website http://www.fubo.tv ? Apparently, they stream a number of Championship matches live, for US$6.99 a month (no long-term commitment required). They say that "fuboTV provides soccer fans with access to ... live matches from La Liga, Serie A, Bundesliga, Ligue 1 and Primeira Liga among other top leagues and tournaments from your desktop, mobile phone, Roku, Chromecast and Amazon Fire TV". If it's true, it might be worth it.
According to https://worldsoccertalk.com/championship-tv-schedule/ some of the upcoming matches include:
Friday, August 7: Brighton vs Nottingham Forest
Saturday, August 8: Leeds United vs Burnley and Sheffield Wednesday vs Bristol City
Sunday, August 9: Preston North End vs Middlesbrough
