Southampton's exceptional start to the season has stunned many, and the poor starts made by Arsenal, Liverpool and Tottenham mean that the Saints have a very legitimate shot at a top four place.
That means that January transfers must be on the agenda for the Dutchman, and so far, he and the Saints have recruited well.
Fraser Forster, Ryan Bertrand and Sadio Mane have all impressed so far, but it's three former Eredivisie players who have caught the eye; Toby Alderweireld (ex-Ajax), Dusan Tadic (ex-Twente) and Graziano Pelle (ex-Feyenoord), as Koeman exerts his knowledge of Dutch football.
Well, there may yet be a fourth to arrive, with the Daily Mirror reporting that Southampton are considering a January move for Twente winger Jesus Corona.
The Mexican international, 21, joined Twente from Monterrey in 2013, and played alongside Tadic for Twente last season, scoring twice in 15 appearances - though only three of those were starts.
A diminutive winger with impressive pace and dribbling ability, Corona would add depth to the wings for Southampton, where cover is needed for Mane and Tadic.
Corona certainly has potential, and with a value of just around £2.5m due to a clause in his contract, Southampton and Koeman could be laying the foundations for yet another transfer success story.
