My fave post-match analyst on TV is probably Gary Neville. He openly hates Liverpool as much as he loves Man U but he's always very good talking about the games.
The best writers are at The Times but they have a rigid paywall. The Guardian's OK but nothing amazing.
There's a weekly hour-long show on Sky that they always put up on yotube, where leading journalists discuss the latest developments. Some people find it a bit dry but I absolutely love it and watch it every week. It doesn't really focus on tactics but it'll be a convenient way of keeping up with all the big stories and general thinking about players, managers, etc.
This is the latest one
