If you want to show your support for your football team on your computer, I found a great set of free wallpapers on Flickr by contributor Hawk Eyes. Check them out here.

Every team has its own wallpaper, with a huge logo and the season's schedule down the right. All the images have a nice slightly aged look and are high quality. There are a range of sizes from tiny thumbnails to postcards and two big enough for your desktop - 1024 x 640 and 1920 x 1200. Some teams even have two color versions, but don't take it personally if your team only has one!
