I have the Eurosport player subscription. PC / Tablet / Phone app.
I use my phone and Chromecast it to the TV.
The chromecast 1080p is perfect, better than Amazon Prime Chromecast (I use the TV app for this, which is fine).
It was on live as it was played, and then it's on demand for ages afterwards.
Here's how it looks now in the phone app on demand. I can go farther back in time through all the matches. These are just a 5 most recent.
Swiping right gets me the 2nd second singles and doubles, if there was one played.
For £19.99 a year it's a no brainer.
I watch the French open and of course, Game, Schett and Mats when it's on
I watch downhill skiing when there's no tennis
Here's what's on live right now for me.
Every event of every sport they cover is there on demand. I watch a fraction of it.
I watch most of the ATP / WTA matches on Amazon Prime. Their coverage is superlative. Can still go back and watch US Open matches I fancy / missed. Great during the off season.
