Arsenal made a terrible start to the north London derby on Sunday afternoon.
The Gunners trailed 2-1 to Tottenham at half-time and their own players were at fault for both goals.
Christian Eriksen tapped in the first after Bernd Leno deflected Erik Lamela's shot into his path.
Some of the blame for the opening goal will fall on the shoulders of Arsenal's goalkeeper for failing to deal with a very saveable shot, but he wasn't the only one at fault.
David Luiz came charging out of position to try and challenge Son Heung-min on the halfway line, while his teammates did a terrible job of covering him afterwards.

But it's Granit Xhaka who will get deservedly get most of the stick should Arsenal go on to lose the game.
He gave away a penalty in the 40th minute after a shocking tackle on Son Heung-min. It may be the north London derby, but there's no room for challenges like it in the Premier League.
Check out the footage below.
Absolutely shocking. Harry Kane made no mistake, dispatching the spot-kick to make it 2-0.
Xhaka's ridiculous tackle was understandably slammed by Gary Neville on commentary shortly after.
"[It's] absolute madness from Xhaka. He does it week in, week out. Season after season. He doesn’t seem to learn," Neville said.
"I don’t think I’ve watched Granit Xhaka play where he doesn’t make 50 fouls per half."
Fellow Sky Sports pundits further during the break, with Jamie Redknapp saying: "It was a ridiculous tackle to make."
"[You've got to] stay on your feet, especially in the box. He's 26 years old. It's something you learn in your first week as a footballer," Graeme Souness added.
Xhaka's teammate Alexandre Lacazette pulled a goal back moments before half-time and with the game finely balanced, there are probably going to be a few more tasty challenges before the end.News Now - Sport News
