On Sunday afternoon, Quique Sanchez Flores' Watford side capped a season of unexpected success with perhaps the biggest scalp of them all: the Hornets dispatched the defending FA Cup holders Arsenal, to book their place in what will be Watford's first semi-final since 2007.
It was an impressive display by the Hornets, who got their tactics spot on to bring the Emirates Stadium to its knees. Odion Ighalo broke his recent goal drought to put the visitors in the lead, before a stunning strike from Adlene Guedioura - a surprise addition to the squad for the tie - doubled the Hornets' lead. A late goal by Danny Welbeck wasn't enough to rescue a replay from the Gunners, as the away end rocked at the final whistle.
Staying humble
"I didn't think too much about it"
- Adlene Guedioura
Guedioura, whose shot rifled into the net past an out-stretched Petr Cech, spoke to Hornets PlayerHD after the game, with the Watford celebrations in full flow. Asked about his goal, the Algerian was - as is the custom from the Watford players this season - typically gracious, offering his thanks to Troy Deeney for doing "well to keep the ball in the box", and stressing that he "didn't think too much" about hitting it.
Yet hit it the 30-year-old certainly did, as the ball flew into the back of the net to send the fans into hysterics. Describing it was one of the "best goals" he's ever scored and saying it was a "great sensation" to score in a quarter-final, Guedioura stressed how it was also one of the "most important", securing Watford's place in the last four and earning them a trip to Wembley Stadium for the semi-finals.
The 12th man
As suspected, over 8,300 fans travelled to North London to pack out the Emirates, and they were in fine voice throughout. Guedioura was quick to draw attention to the fan support, saying it was "really nice" to hear them so vocal. The midfielder teasingly suggested that he thinks the fans might have just "enjoyed it", and opened up the idea of hopefully giving them something to enjoy again in the semi-final, and "maybe even further".
Make no mistake about it: Watford are riding a wave and will fancy their chances of going all the way and lifting the FA Cup, an achievement that would be incredible given the small expectation on them this season. It is a reflection of their campaign and spirit that not many would bet against it.
