Manchester City versus Liverpool has been the standout rivalry in English football over the last decade, and in the last five years it has been the top rivalry in Europe too, even surpassing El Clasico in terms of quality of football, star names, tension and drama.
The two rivals have contested three enthralling title races and one unforgettable Champions League tie, and when it comes to entertainment, the fixture almost never disappoints.
And after more than seven months apart, these most intimate of enemies meet once more at the Etihad Stadium on Saturday, and they do so once again as title rivals, separated by just one point at the top of the Premier League table.
