Ok, assuming that you already sync your N900 calendar with Google Calendar:

1) Go here and download the .ics file containing the fixtures: http://news.bbc.co.uk/sport1/hi/foot...10/8677077.stm

2) Go to Google Calendar and go into Calendar Settings

3) Click on Import Calendar

4) When the dialogue window open select the .ics file you have just downloaded

5) Just choose import to append to your default calendar or choose a different calendar if you have setup more than one in Google.

6) Synchronise your N900 calendar if you wish to see it update straight away
