Liverpool will go ghost hunting on Sunday - looking to slay the demons of Chelsea past.
Because Anfield has been a Premier League fortress for almost two years.
But while Manchester City, PSG, Manchester United and Arsenal have all been annihilated at Anfield, Chelsea haven't .
And they are the most difficult obstacle now standing between Liverpool and a potential first Premier League title.
If Liverpool have had one Anfield bogey side in the last few seasons it has worn blue.
The Reds' only home defeat this season? Chelsea in the Carabao Cup.
The only team Liverpool haven't celebrated victory at Anfield over since May 8, 2012? Chelsea.
And let's not even mention 2014 .
The London Blues have had six managers since Liverpool last beat them at Anfield.
That victory was so long ago that Daniel Sturridge was a Chelsea player, making way after 67 minutes for Romelu Lukaku.
Jordan Henderson, who scored Liverpool's second goal that day is the only player still at Anfield who was in the Liverpool squad that day.
But Liverpool have already gone ghost-busting this season.
Prior to December's visit of Manchester United to Anfield the Reds hadn't celebrated a league win at Anfield over one of their fiercest rivals for six years - since September 2013.
But Xherdan Shaqiri's intervention buried that bogey.
Now they will be aiming to scratch another seven-year itch.
And they have proved already this season that they are in the mood to do just that.
