It has been a rivalry that has defined the last five years of English football and no other teams look likely to catch them any time soon.
Through a combination of near-perfect recruitment, expert administration and sublime coaching, Manchester City and Liverpool have left every other side in the Premier League — if not Europe — in the dust over the last half-decade. The two are on course to meet in this season's Champions League final which would set the notion in stone.
Regardless of whoever lifts the famous trophy and whoever runs out triumphant in yet another epic title race, there is very little to split the two. The rivalry may not go down as the most hostile or ferocious in Premier League history, but it's hard to argue that there have ever been two sides as good as these two locked into such an enthralling battle.
