Arsenal were nothing short of shambolic during Saturday's 2-1 defeat to Watford.
Per Mertesacker gave the Gunners a 1-0 lead in the 39th minute and for the most part they looked comfortable at Vicarage Road.
But with 20 minutes remaining, they capitulated. Hector Bellerin gave away a penalty in the 71st minute, which Troy Deeney converted, before Tom Cleverly struck a winner in injury time.
Arsenal can feel hard done by for the penalty because Richarlison went down far too easily under Bellerin's challenge, but in the end they deserved to lose.
Arsene Wenger was seething in his post-match conference and described Neil Swarbrick's decision as "scandalous".
"The decision on the penalty is a bit ridiculous and then we panicked a bit for their second goal and in the end we stand with a defeat," said the Frenchman.
"It is a scandalous decision, but what can we do about it? Nothing. We can talk and talk and talk. At the end of the day they scored.
"It was not a penalty, it was a creation of the referee. The decision is wrong and that's it. And it came at an absolutely important time for them. No penalty, no goal."
Arsenal's players could have no complaints about Cleverly's winner, though, especially Granit Xhaka, who was to blame for the goal.
Watford were denied three times before they found the back of the net but when the ball fell to Cleverly, Xhaka was static and made no attempt to track his man.

XHAKA AT FAULT
However, in the 24 hours since Arsenal's defeat, football fans have noticed something even more embarrassing about Xhaka's role in the goal.
A close-up video has revealed that Xhaka was actually picking his nose when Cleverly scored his winner - no, seriously.
'TOO BUSY TO DEFEND'
Shocking. Arsenal fans have been calling for Wenger to start Jack Wilshere in the Premier League and now they've been given even more reason to think that way.
Xhaka cost his side a valuable point against Watford and deserves to be punished for it.
