A competitive afternoon at Vicarage Road saw Southampton edge the game 1-0, with Ché Adams the sole goalscorer. Adams’ top-corner finish put the south-coast side ahead after 20 minutes, and that would prove to be the difference.
Watford went close through Cucho Hernández, Ismaïla Sarr and substitute Ashley Fletcher, but weren’t able to get their goal.
The visitors also had opportunities to add to their tally, but Ben Foster stepped up to produce several goal-preventing saves.
Claudio Ranieri’s hosts weren’t able to get a point from the game despite their efforts, and will now look to their next match away at Arsenal next Sunday.
The Saints enjoyed a handful of early chances, testing Foster in the Watford goal. Nathan Redmond’s cross in the first minute had to be stopped by the Hornets No.1, after Craig Cathcart’s block went goalward. Oriol Romeu’s effort was later blocked by captain Moussa Sissoko, and Adams hit the side netting with his shot.
The Golden Boys were looking to hit their visitors on the break, and found the target on a couple of occasions. Joshua King was unlucky not to get on the end of João Pedro’s cross, and Hernández’s free-kick tested goalkeeper Alex McCarthy.
Adams made up for his earlier miss on 20 minutes, netting the opener with an impressive curled strike.
Watford came inches away from an equaliser thanks to a direct move. Foster launched a driven pass to King, who managed to find Sarr in the box. The winger managed to get a shot off, but it deflected off the inside of the post and off Kyle Walker-Peters to safety.
