Want to know how to set a UEFA Champions League record? Decide you are going to run faster than everyone else and do it earlier in a match than anyone has every done it before. That's what Alexandre Pato did, essentially just out-running the Barcelona defense to get in alone on goal and finish, doing so a mere 23 seconds into the match. Yup, that would be a new Champions League record for quickest goal and it has also stunned "invincible" Barcelona at the Camp Nou. Run, Duck, run!
Pretty much everyone agreed that Milan was the most dangerous team in Pot 2 during the draw and this is why. There aren't a lot of teams outside of Pot 1 with someone like Pato who can go ahead and just score a goal on his own. Barcelona have a real battle on their hands now and they still have to stop the Duck for another 89 minutes and 37 seconds. Good luck.
Edit: Well Mr. TV announcer was wrong. This isn't the fastest goal ever because this is the fastest goal ever. Still, 23 seconds is pretty fast.
