For those of you who watch the matches on TV or online, come join your fellow COS readers this Sunday for our West Ham vs Arsenal liveblog! (Don’t forget to set yourself a reminder via the widget above).

The first ever COS live blog was last weekend for the Arsenal vs Everton match and was a raging success, with many of you joining your fellow readers to comment on the game.

We’ll be embedding a chat window into a post an hour before the match starts, thanks to a tremendous bit of technology from the lads at Cover It Live.

This isn’t the usual liveblog where a writer updates the post, and then you have to add comments. CoverItLive means that one of the COS writers will be live blogging the entire game, but you’ll be able to add your thoughts to the chat window in real time and see the opinions of your fellow fans as the action unfurls. No plugins, no downloads, you just turn up and it’s all live on the page.

In true COS style, it’ll be both West Ham and Arsenal fans in the chat at the same time so you’ll get both sides to every card, every questionable call and every goal.
