Currently, the longest Champions League run of any Premier League club is with Manchester City, a seven-season stretch starting from 2011-12.
After that? Tottenham: two years. Liverpool, Manchester United and Chelsea made it this season, but not last. Leicester and Arsenal last season, but not this. Nothing can be guaranteed in the Premier League with six clubs, minimum, vying for four spots.
Compare that uncertainty to the sense of security felt on the continent for clubs such as Bayern Munich, (10 straight Champions League campaigns), Barcelona (14) or Real Madrid (21). Factor in that the grip of the biggest teams in many of Europe's major leagues is only getting stronger, then add emerging powerhouses such as Paris Saint-Germain and a reborn Juventus, now recovered from the Calciopoli crisis.
