Less than a year after Leicester City’s incredible and unexpected Premier League victory, it is no surprise to see that they have failed to maintain that level, but their collapse has been astonishing.

From the first 20 games of 2016/17, Leicester managed to collect just 21 points, 19 fewer than they had at the same point in their title winning season.

While their moment at the summit was fleeting, an incredible 2-0 victory over Sevilla in March saw Leicester reach the Champions League quarter-finals, meaning this season might turn out to be as remarkable as the last, even if it is for very different reasons.

As extraordinary as it may seem, they are not the first champions to suffer a major hangover after winning a title, and it is not restricted to the UK either.

Italy, Germany, and even some international sides have felt this most unwelcome of comedowns over the years.

Here are six other champions, other than The Foxes, who failed to live up to expectations the next time round…

Bayern Munich – 1974/75

If the sacking of Claudio Ranieri felt like an undignified end to a manager’s tenure, imagine the indignation of Bayern Munich fans in 1975.

Starting in 1971, Bayern won three consecutive Bundesliga titles, and in 1973, won the first of three consecutive European Cups.

Under manager Udo Lattek, it seemed that Bayern would continue to dominate. It must have come as quite a surprise when they finished the 1974/75 season in 10th place.

After a slow start cost Lattek his job, the team never recovered domestically, but they did defeat Leeds United to win the 1975 European Cup.

Nevertheless, the balance of power in Germany shifted with his sacking. The following season saw Lattek hired by rivals Borussia Monchengladbach, winning the first of two Bundesliga titles in a row as Bayern floundered in mid-table for the rest of the decade.

Chelsea – 1998

The big collapse that comes to mind with Chelsea is the 2015/16 title defence that saw Jose Mourinho fired for a second time and Chelsea pick up just 15 points from their first 10 games.

But there is another which, it could be argued, is the shortest defence of a title in recent memory.

After winning the FA Cup in 1997, nobody expected the holders to go out at the third round stage. With 64 teams in the third round draw, it was supreme bad luck to be drawn against the reigning league champions, Manchester United.

The 5-3 final score makes it look like a classic, but in truth, being 3-0 down at half-time meant Chelsea’s title defence was as good as over after just 45 minutes.

While Chelsea did stage a late comeback, they were 5-0 down and United had their minds on the next round.

France – 2002

After the delight of winning the nation’s first World Cup in 1998 on home soil, the French domination of international football continued as they added the UEFA Euro 2000 title.

Heading into the 2002 World Cup, most people expected France to make a strong defence of their title.

However, a shock defeat to Senegal in their opening game sent France into a downward spiral.

They failed to qualify from the group stage after achieving just one point and failing to score a goal.

FC Nurnberg – 1968/69

What is required to reach a summit is rarely the same as what is required to stay there and it is not unusual for a title winning team to struggle the following season.

This means it is essential to continue developing. Of course, it is possible to go too far and remove a team’s identity.

In 1967/68, FC Nurnberg won the German title. Looking to create a dynasty, manager Max Merkel tried to overhaul the team to focus on youth, adding 13 new players to the squad the following season.

Rather than reinforcing what had worked previously, this influx of new players destroyed the title-winning team.

They were relegated on the final match day of the following campaign.

Manchester City – 1937/38

The 1936/37 season saw a dominant Manchester City team stroll to the title on the back of a 100 goals and a 22-game unbeaten run, but this is not why they are in the history books.

Despite being the league’s top scoring team with 80 goals, City became the first, and only reigning top-flight champions England has ever seen relegated.

No matter where Leicester finish in the 2016/17 season, this is one record their fans will be hoping they don’t emulate.

Aston Villa – 1981/82

Leicester are not the only English champions to find the distraction of European football helped to ease their disappointment of their poor title defence.

1980/81 saw Ron Saunders’ Aston Villa win their first title for 71 years before slipping off the pace and finishing 30 points adrift the following season.

In a strange parallel, both Villa and Leicester chose to sack their respective title-winning managers in February, with their replacements stopping the slide domestically and enjoying a successful European campaign.

Villa’s run saw them win the European Cup in 1982, so perhaps Leicester’s debut Champions League campaign this season could lead to something even more remarkable than their Premier League title.
