Unlike Antonio Valencia yesterday, Zenit's Tomas Hubocan was looking more Jake LaMotta than Rocky after Robert Lewandowski opened a vein with an unfortunately well-timed knee to the side of the head. Soccer is a blood sport.

Here are some pictures of the damage:

Despite laying there like a newborn baby for a couple minutes, all types of blood streaming down his face, Hubocan was not substituted and continued with the game. You never got me out, Rob.
