One of Swansea City's best bits of summer business has quietly gone under the radar
Watford, having been second best for most of the night, were now starting to push.
Having dominated the contest for so long, and scored a deserved opener, Swansea City were now having to dig in a little.
Two minutes from time, the Hornets won the latest in a flurry of corners. In it came, curling menacingly into a penalty area now swelling with expectant Watford bodies, each of them ready to pounce.

But rising above it all was Lawrence Vigouroux, muscling his way through the chaos to duly pluck the ball out of the air and snuff out the danger.
It was a moment that provoked one of the loudest cheers of the night, and saw him earn a slap on the back from almost every one of his visibly appreciative team-mates as he lay on top of the ball inside his own box.
Vigouroux wasn't actually forced into a save on the night, but this was nevertheless a contribution that helped edge Swansea over the line to claim what was a largely deserved three points.
The Chile international has perhaps gone under the radar a little since his arrival from Burnley, particularly given the form of other arrivals, such as Goncalo Franco or Eom Jisung. But the number of plaudits he's attracted in recent weeks have made him increasingly harder to overlook.
Some of the club's more excitable supporters have even started making comparisons to the likes of Lukasz Fabianski.
There's some logic to that claim. At one stage, no goalkeeper in the Championship had kept out as many goals as the 30-year-old, a record that has clearly been a key driver in Swansea's superb defensive record this season.
"We're grateful as he's a great goalkeeper but we'd like to give him less to do," Williams said when quizzed about the form of his number one earlier in the season.
On the evidence of Tuesday night, Swansea are making progress on that front.
"I am lucky because we've got such a good defence here, and they make it easy for me," the keeper said.
"The defensive record we have is credit to the players in front of me, they show great intensity in front of goal.
"They work so hard, and they put their bodies on the line. I'm lucky enough to make the saves they allow me to make."

His form has seen him pushed back onto the scene with Chile, whom he'll link up with once again over the coming international break, and it's clear he's keen to continue making the most of the chance he has been given with the Swans, having gone round the houses a little in his club career up to this point.
“This is a really big opportunity for me, there’s no doubt about it,” he said.
“It has taken me a long time in my career to get back to this level, and I know I simply have to make the most of it.
“I am working with a coach who gives players so much confidence to express themselves on the pitch, and who I loved working with at Swindon.
“I also get to work with the England goalkeeping coach (Martyn Margetson) every day, so there are no excuses for me.
“I have got to work hard to prove myself and improve myself every day, there are really good goalkeepers here so, if I want to play regularly, I have got to be ready for that battle."
