There is something special about Liverpool's Anfield on European nights as it transforms into a swirling cauldron of noise capable of inspiring its hosts and intimidating their foes as Manchester City discovered on Wednesday.
Big games create big atmospheres, but the noise level inside the stadium for Liverpool's 3-0 victory in the Champions League quarter-final, first leg was noticeably louder than for the January league clash between the two clubs.
European success is in Liverpool's DNA and their supporters feel it. A banner in the Kop end reminded everyone of the five European titles won by the club.
On Wednesday, City looked rattled, not only by the early goals but by the febrile atmosphere before the game, inside and outside the stadium.
City fans will be hard-pressed to match that atmosphere at their 15-year-old home, the Etihad Stadium, on Tuesday for the return leg.
Yet if part of Anfield's magic on European nights is linked to history, then City have a chance to start creating their own -- if they can produce the unexpected comeback required to advance.
