Arsenal have had a torrid time against Liverpool in recent seasons.
And this season has been no different.
The match at Anfield proved to be a difficult encounter for Unai Emery's men as they fell three goals behind.
Joel Matip opened the scoring in the first half before Mohamed Salah took centre stage.
But Salah was given a huge helping hand by a certain David Luiz.
Luiz joined the Gunners from London rivals Chelsea during the summer transfer window for a fee in the region of £8.5million.
It was a surprising move, with no indication that he was going to leave the Blues to join the Gunners until late on in the window.
Luiz missed the first game of the season against Newcastle United, but was handed his first start in the game with Burnley, helping his new team keep a clean sheet.
But he was at fault as Arsenal fell behind against Liverpool in their first big game of the season.
It was 1-0 at half-time at Anfield, but within minutes of the second half starting it was two, when Luiz foolishly pulled Salah's shirt in the box, with a stonewall penalty awarded, that Salah converted with aplomb.
Salah then raced through to make it 3-0, driving through the Gunners defence before slotting past Bernd Leno.
And with Arsenal expected to battle it out with the likes of Chelsea for a place in the top four this season, his faux pas did not go unnoticed by the Blues supporters.
The Chelsea fans certainly enjoyed what they were seeing.
