Watford returned from the international break sitting pretty in eighth after a fantastic start to the season that has seen them lose just once, to Pep Guardiola's rampant Manchester City.
However, in Arsenal, they faced yet another test of their mettle under new manager Marco Silva with the Gunners entering the game on a seven-game unbeaten streak. The North London club have been resurgent since their 4-0 drubbing at Anfield and would have considered themselves as favourites ahead of the Vicarage Road tie.
Things were going well and truly to plan for the Gunners as well after Per Mertesacker rose highest to power a header past Heurelho Gomes to take the lead.
From then on in Arsenal maintained some semblance of control but it was always going to be a nervy lead to try and hold onto.
After coming off the bench, the much-maligned Mesut Ozil missed a glorious chance to double his sides' advantage and from the resulting break disaster struck for the Arsenal.
Brazilian starlet Richarlison went down under pressure from Hector Bellerin in the Arsenal box and the referee duly pointed to the penalty spot. Replays showed that Richarlison went down a bit too easily and it was clear to see why Bellerin was less than pleased with the decision.
Captain Troy Deeney stepped up to convert the spot kick in the 71st minute before Watford would eventually go on to take all three points late on through a Tom Cleverley winner.
All the talk post-match surrounded the award of the penalty though. Arsene Wenger felt his side were extremely unlucky and branded the decision "scandalous", but it was the comments of Watford's skipper that will take all the headlines.
Speaking with BT Sport after the game, Deeney was asked to comment on what he thought of the penalty after Hector Bellerin had stated that it was not a penalty at all. Deeney's response did not disappoint.
Deeney's comments will go down a treat in Hertfordshire, but maybe not so much at the Emirates Stadium!News Now - Sport News
