After two weeks off, the Premier League didn't miss a beat. Week 12 was another exciting one in England that saw the last two undefeated teams, Manchester City and Newcastle, square off, as well as what has recently become one of the biggest matches on the calendar, Chelsea versus Liverpool.
Arsenal continued their quiet climb up the table with another victory, Manchester United maintained their not-so-impressive but nonetheless effective form and Chelsea's defense continued to fall apart.
At the other end of the table, Bolton, Blackburn and Wigan all sit in the relegation zone with fewer than 10 points from 12 games, so it's probably safe to say at least one of them won't be climbing out anytime soon.
December is a pivotal month for Premier League clubs as fixtures start to pile up, and it becomes harder to overcome point differentials in the new year.
So, what did we learn in Week 12 of the Premier League?
