Watford continued their unbeaten start to the league season with a 2-0 win at Southampton to climb into the top four.
Both teams began the game with two draws and a victory from their opening three league games.
But it was Watford whose record remained unblemished after their St Mary's head-to-head.
Meanwhile Mauricio Pellegrino's Southampton side were booed off as their search for momentum and genuine signs of progress since his summer appointment continue.
Watford took the lead in the 38 minute with a goal that was out of keeping with a low quality first half.
Southampton failed to clear a long throw in and Abdoulaye Doucoure eventually latched onto the bouncing ball and volleyed it past Fraser Forster from the edge of the box.
And Forster was beaten by another long ranger in the 66 minute when Watford sub Daryl Janmaat drilled a 25 yard effort into the bottom corner five minutes after coming on.
Watford had chances on the break to heap more misery on Southampton who were left grateful to Jack Stephens for a last-ditch tackle to deny Richarlison a third.
And a frustrating afternoon for Southampton was summed up when the home fans sarcastically cheered Cedric finally forcing Herurelho Gomes to make a save in injury time.
Watford manager Marco Silva has joked that the pressure of Premier League management pales in comparison to his tenure at Olympiacos.
Silva, whose Watford side head to Southampton on Saturday unbeaten from their opening three fixtures, spent one year in charge of the Greek team.
The 40-year-old Portuguese won 17 consecutive league matches as Olympiacos manager - en route to winning the title with six matches remaining - and even recorded a 3-2 Champions League victory over Arsenal at the Emirates Stadium.
But Silva unexpectedly quit on the eve of his second campaign in charge at the club, citing personal reasons, before ending up at Hull six months later, and subsequently Vicarage Road for his second challenge in England’s top flight.
“It is an amazing job, but it can be the job with the biggest pressure,” Silva said ahead of his side’s trip to St Mary’s Stadium.
“When I played you felt similar pressure, but it is different when you are a coach as everything is done under your control.
“But that is football. In Greece, it is a little bit worse. And in Portugal it is more or less the same as the Premier League. It is our life and the life of one manager and one coach is always the same.
“We need to prove ourselves day-by-day, game-by-game, and it is important that we believe in our philosophy, our idea and convince our players to believe as well.
“We try to win every match, but we know that is not possible and you have to react after a bad result. When you take good results and important points it is better because everyone has confidence.
“It is not perfect. It is not the best way. But it is normal in football that you have pressure if you don’t achieve some results.”
