Southampton will head into the international break top of the Championship after an emphatic victory over Watford at St Mary's.
Rickie Lambert put the Saints in control with a brace of penalties - the first awarded for handball against John Eustace, the second for a foul on the striker by Adrian Mariappa.
Guly Do Prado's fine finish ensured there was no way back for the Hornets.
And substitute Lee Holmes' long-range strike put the gloss on the victory.
The win maintains Southampton's 100% home record this season and gives them their best start to a season in 52 years.
It is an impressive record, especially for a side making their return to the Championship following a two-year spell in League One.
However, they made a sloppy start to this match and could have fallen behind on a number of occasions.

- 1 Oct: 4-0 v Watford
Mariappa headed wide early on for Watford, before Jonathan Hogg's shot from the edge of the area was saved by Kelvin Davis, who also superbly tipped over from Joe Garner's lob.
Having weathered the storm, Southampton grew as a force in the game and took the lead midway through the first half when Eustace's handball gave Lambert the chance to convert from the spot, which he did with aplomb.
The big striker hit the post with a header soon after and Adam Lallana crashed a long-range drive against the crossbar as the Saints finished the half strongly.
They added to their lead 10 minutes after the break when Lambert won another penalty after being brought to the ground by Mariappa as he tried to latch on to Frazer Richardson's cross.
Lambert picked himself up and fired the spot kick home.
Guly ensured Nigel Adkins' side the victory with 20 minutes to go when he picked up Lallana's pass before placing the ball into the right corner.
And their attacking approach was further rewarded with two minutes remaining when Holmes' curling effort from 25 yards found the net.
