As it turns out, it can mean much more than just that one thing, but more on that later. For now, let's enjoy a bit of Tunnel Cam action. And who doesn't love the Tunnel Cam?
If you're not familiar, it's basically an unassailable fact that Manchester City have the best Internet department of any Premier League club (and possibly any football club in the world). From an engaging Twitter account, to a stylish, informative, and fun web site, to a best-in-class YouTube channel, City spoil their fans by offering lengthy, innovative, and engaging content. There's absolutely no reason for us to be stuck with short video snippets in this day and age - an idea that sadly still has not registered itself at Chelsea.
The Tunnel Cam is just one of the many regular video features on offer from Manchester City. Other clubs (and even the FA) are catching on quickly as well. As the name implies, it's a highlight reel of "behind-the-scenes" action from the tunnel from both sets of players before, during, and after the game. Just another way to make you feel more in touch with your club.
Watch out for Serbian bearhugs, a bit of vocal leading from Hart and Kompany, Nasri getting some love, Lampard seemingly not camping happily (last out, first in), and Eto'o continuing to exchange all the shirts as he makes his farewell tour around the world (a notion that Touré doesn't seem to appreciate as much). Even André Schürrle makes a cameo.
