Liverpool's 68-game unbeaten home run in the Premier League came to an abrupt end on Thursday evening after Ashley Barnes' late penalty secured an unexpected 1-0 win for Burnley.
For over three years, Jurgen Klopp's side had avoided defeat at fortress Anfield, a quite incredible achievement.
Many believed the Reds would go on to match Chelsea's 86-game unbeaten home record in the Premier League, but the current champions just fell short.
The Blues' run will probably never be equalled by an English team, especially given how competitive top-flight football is in the country.
However, in the 21st century, Chelsea's run of 1,709 days without a home league defeat is only Europe's second longest.
Let's find out which team takes top spot...

1. FC Porto (2008-2014) - 1,947 days
Porto's incredible unbeaten home run came just 243 days short of six full years, absolutely ridiculous stuff.
The Portuguese side's record will simply not be equalled or surpassed by any team in one of Europe's top leagues and the same can probably be said about Chelsea's.
To be honest, Liverpool's 1,369-day run will likely stand the test of time as well and the fact they achieved it in a fiercely competitive Premier League is quite remarkable.
They're going through a rough patch right now, but never forget that Klopp's side are one of the greatest we've ever seen.
