That win against Everton showed once again that work rate is at the basis of Liverpool's success.
Everton have probably a mental block but Liverpool pressed and ran much more than them which was key. Liverpool are first and foremost about exceptional fitness levels. Easily the fittest team/players in the world. This is what distinguishes them form other top teams, i.e. Barca, Madrid, us...
Everton were probably tired from the crazy Chriistmas schedule but that's a pure excuse for their performance in the 2nd half. They couldn't exchange 3-4 passes and hold on the ball. It was all about long balls upfront. Very poor.
