Let's exclude teams that got relegated due to non-sporting reasons like Juventus 05/06. I'm looking for cases were seemingly strong teams and/or teams with well known players got relegated. Examples could satisfy both criteria or only one, just post everything that might be interesting. Fiorentina had some amazing players in 1992/93 when they got relegated. Brian Laudrup, Dunga, Batistuta and Effenberg. Kaiserslautern's finishes in the mid 90s look really odd. 2nd in 93/94, 4th in 94/95, got relegated in 95/96, but won the DFB-Cup that season. Got promoted immediately and won the Bundesliga in 1997/98. Manchester City got relegated in 37/38 after winning the league in 36/37. Not sure how their squad changed. There was just a lot of parity at that time, City were 4 points from finishing 12th out of 22 teams and had a positive GD. The most remarkable stat however is that they finished 1st in goal scored! Nürnberg is another team that got relegated (68/69) after winning the title (67/68). Just like in City's case the bottom half of the table was really close together. Atletico Madrid in 1999/00 had a lot of familiar names. Hasselbaink, Molina, Carlos Gamarra, Baraja, Solari, Valeron, Capdevila, Kiko.... Another squad with famous players who got relegated (which should be well known though) is Man United in 1972/73.
