The year was 2005: Neither Lionel Messi nor Cristiano Ronaldo had even played in a FIFA World Cup. George W. Bush was in the the beginning of his second term as president of the United States, YouTube was just founded and the world was dealing with a differently deadly virus -- the bird flu. That was the last time soccer fans saw a UEFA Champions League quarterfinal round without Messi or Ronaldo ... until now.

Messi's Barcelona were edged by Chelsea in the round of 16 in 2005 and Ronaldo's Manchester United fell in the same round to eventual runner-up AC Milan. This week, Ronaldo's Juventus were booted from the competition by Porto and Messi's Barcelona exited the stage after by PSG. 

To put into perspective as to how rare this is, when neither team made the semifinals last season, that was the first time we hadn't seen at least one of them in the last four since 2004-05. Heck, to be fair, the last time this happened Messi wasn't even a key member of Barcelona's UEFA Champions League squad, having only made his debut earlier in the competition against Shakhtar Donetsk.
