Sokratis Papastathopoulos' mistake vs Watford has got Arsenal fans talking
With the Gunners leading 2-0 at the break thanks to a brace from Pierre-Emerick Aubameyang, the last word in the dressing room at half-time would have been not to give the hosts a sniff.
It would appear that Sokratis wasn't paying attention.
As the visitors looked to play the ball out from the back, the Greek defender took a huge chance by feeding the ball into Matteo Guendouzi.
However, he underhit the pass and the visitors were in trouble.
Former Manchester United midfielder Tom Cleverley read Sokratis' intentions as he intercepted the pass to reduce the deficit and leave Arsenal fans fuming.
Take a look at some of the responses on Twitter.
