For cricket bollym4u.com works well but lots of ads. As the name suggests its Indian coverage but 95% of the time its in English. They actually had the recent one day series between Australia and Sri Lanka on star sports Asia. I pay 6rmb to get it every month and the package comes with espn as well as a few movie channels.

The six nations will be broadcast on the bbc website so I'd get yourself a VPN and watch it on there. A VPN will also allow you to listen to test match special.

Watch football in the peoples restricted china?

I'll expect youtube to be working before that is possible.

Never played football in my life, Foxy Poster; we were always taught that football was strictly a recreation for the lower orders. No, rugby and cricket were the only choices at my school.

The same applied to me, but I always preferred football to rugby. In winter I opted for cross country running rather than rugby, but was caught once hiding in bushes just before our first lap round a park was to have taken place. My plan worked all but once - rejoin the runners at the back after 2 laps and well behind the teacher!
The only sport on offer I liked was cricket - once took 3 wickets in 4 balls as a spinner playing for my school's fourth eleven. A right fluke!

Do you have a link for free rugby and cricket?

Nope, I don't. Try googling 'free rugby (football) live streams' and 'free cricket live streams'.
