how can i watch the premiership matches every week that are being
broadcast live overseas featuring my club manchester city but are not
being broadcast live on my sky and sky+ packages

Try a different satellite provider? Or, you could try listening to an
internet radio broadcast of the match, or a live text based
scoreboard. I know that these really dont compare to watchin the match
itself, but it would be almost impossible to find an internet site
which broadcasts the matches, as the rights to do so are very
expensive.

This site might help:

I can't see that Manchester City would have much of a following
anywhere in the world, except a very small part of Manchester ... but
why not contact the club?

You should also tell them where you are living.

Now, if you supported Oldham Athletic, you would probably have many
more options .....

Best of Luck!

There are satellite TV football listing including Man City at

To view the channels you might need a larger and rotatable dish to
point to the appropriate channel. I don't know which channels are
encrypted and which are clear.
