If you missed it last week, Liverpool manager Jurgen Klopp was accused of ordering his ground staff to only sweep away snow on his side's attacking end of the pitch at half-time against Leicester City.
It didn't go down well with many.
The teams went into the break a goal apiece on a pitch that had been clearly affected by the sub-zero temperatures, but Liverpool's ground staff clearly had a plan.
Was Klopp using some next level pitch shithousery that we all know and love?
Well, his team got a taste of their own medicine at the London Stadium on Monday night.
It is believed that the ground staff repaired the divots in the half of the pitch that West Ham were attacking while the Liverpool half was left unattended.
Well, you did it last week, lads.
Sadio Mane opened the scoring thanks to a magnificent piece of skill from Adam Lallana on the touchline, but the goal caused plenty of controversy when replays clearly showed James Milner in an offside position.
It didn't take long for West Ham to bounce back though.
Six minutes later, Michail Antonio leveled the tie with a tidy finish from inside the box.
Thoughts on the actions of West Ham's ground staff? Will Liverpool win the Premier League after a dodgy spell of late?
Let us know in the comments.
