Following the Saints 2-0 victory over Leicester on Saturday, they now have 25 points from 11 matches - the club's best ever start to a top flight campaign.
The Saints have so far defied pre-season expectations, winning eight and losing just two of their opening eleven league matches.
Ronald Koeman’s side were written off after a less-than-ideal summer, during which they lost a multitude of key players, including captain Adam Lallana, Rickie Lambert, Dejan Lovren, Luke Shaw and Calum Chambers.
Nonetheless, the Dutchman's summer reinforcements have had an absolutely tremendous impact.
The duo of Graziano Pelle and Dusan Tadic - both signed from the Netherlands - as well as Saido Maine, Ryan Bertrand and Toby Alderweireld have all been integral to the Saints excellent start.

Out-of-form Leicester were the latest to fall to Koeman's side, with Long the difference after netting twice shortly after his introduction as a second-half substitute.
The 2-0 win keeps Saints within four points of leaders Chelsea in a very respectable second place.
It is perhaps slightly premature to suggest Southampton can hold on and achieve a top four finish this term, yet early signs are highly convincing.
Thus far, the club have faced just one of last season's top four sides - suffering a 2-1 defeat to runners-up Liverpool at Anfield on the opening day of the season.
Nonetheless, based on recent form, the club and players will be more than confident of getting results and maintaining the pace alongside the Premier League big boys.
