West Ham vs Charlton
I can't be bothered with a match preview, the BBC has one here and there are many more out there on the wild wild web. Your guess on the final teams is as good as mine, we've got some injuries, Charlton have got some injuries, we've got some new players, Charlton have new players, we know we have the better team but it won't be a stroll in the park.
Pre-season (still feeling confident prediction): West Ham 3 Charlton 1
Radio link: BBC London (last year internet coverage from the BBC was restricted to UK listeners only - there is no warning of this on the BBC site this year but I assume the same applies.
Streaming Video: There doesn't seem to be any free live streaming of the game, but there is delayed coverage of the full game from 17.30 via PPstream, PPlive, SopCast and TVAnts - links to all of these can be found at Football Streaming Info (requires registering but is free to do so).
