It's an emotional roller coaster for Saints fans
The league's 'surprise outfit' are playing superbly under Pochettino - but this has attracted the big guns' covetous eyes
There should be a medical condition recognised for the symptoms currently afflicting supporters of "the surprise outfit" of this season.
Watching Southampton ride high in fifth induces an emotional roller coaster of jubilant ups and anxious downs.
Perhaps this disorder can be labelled "Pochettinotitus" in honour of the manager who has introduced a sublime and exotic style of play never before seen in this old port city.
Granted, it's is a bit of a mouthful. But the numerous syllables and intonation captures perfectly the stomach-churning on St Mary's terraces.
This time last year, the club were anchored to the basement and sinking further into the Solent mire faster than King Henry the VIII's flagship the Mary Rose, which went down in the salty brine not so far from the stadium in 1545.
Nine games into this season and Southampton have given the EPL summit a refreshing topsy-turvy appearance. The script is being rewritten and this bold new narrative is mirrored in the prodigious posters that adorn the side of the stadium as we head towards the turnstiles.
"Our Time Is Now" one declares. "Our Dream is Real" another asserts - big character slogans that would have made Chairman Mao's chief calligrapher beam.
We have no cause to question the propaganda. Southampton's defensive record is the best in the league and the second best in Europe so far this season.
Southampton have only conceded an impressive 0.29 goals per game, one place behind Roma (0.14) and one above Bayern Munich (0.38).
The Saints have let in fewer goals than Lille (0.44) and Barcelona and Atletico Madrid in joint 5th on (0.75).
Why go all the way to Spain to yell "Ole" at every slick pass of the ball when you can simply cross the Itchen River footbridge in the autumn drizzle to find your way to tiki-taka heaven? From the family section to the diehard Stand Up campaign supporters behind the goals, to the sandwich nibblers in the executive boxes, Saints fans sung as one during the 2-0 home win against Fulham.
And who can deny us a chorus of "let's all have a disco" and indulgence in silly dancing whenever the opposition succumbed to our high-pressing game and rock solid defence? For once, siblings were not turning crimson and away in shame at the sight of their pot-bellied dads doing an embarrassing jig. They applauded and joined in.
It is not just the squad's bewitching play that fills our hearts but the friendship among the players. The camaraderie is palpable and highly infectious. We read with glee the stories of fractured dressing rooms stuffed with egos at the rich clubs.
How high can the Saints go under Argentine manager Mauricio Pochettino, strangers in red and white scarves ask each other? Are European nights nigh? Pochettino replies: "The sky's the limit."
Yet as we enter uncharted orbits, powered by thrilling football, bonhomie and winning ways, meteorites of horror and dread are on the radar.
Another impressive show away to Stoke on Saturday should see an end to the "surprise outfit" tag because Southampton's form can no longer be seen as a fluke. And that exposes the team to more scrutiny.
Southampton's impressive academy has produced the likes of Gareth Bale and Theo Walcott. But instead of putting such golden products on the market as in the past, over the last 12 months the young apprentices have been blended with record breaking buy-ins; the club twice broke its transfer record in the summer and was the fourth biggest net spender.
"It was clear from the beginning when [club chairman] Nicola Cortese called me that we were going to focus on the academy, strengthen it and use as much as we can from it," said Pochettino this week.
This strategy has produced a very special battling Band of Brothers which has reshaped the club's present and future. It has also brought widespread interest, and therein lays the downside of success.
We can feel the richer teams' scrutiny and are bracing ourselves for their pillaging during the January transfer window.
Teenage left-back wonder Luke Shaw, 18, has already been linked with a £23 million (HK$285 million) move to Chelsea and Manchester United, while the impressive captain, Adam Lallana, 25, has been targeted by Liverpool.
Both are products of the academy, as is 18-year-old midfielder James Ward-Prowse, who with an estimated price tag of £8m has Arsenal scouts tailing his every darting run.
Striker Jay Rodriguez, 26, is valued at £10m and has interest from Newcastle, while right-back Nathaniel Clyne, 22 - who was bought for £1m from Crystal Palace and is now valued at £7m - is in the sights of Chelsea and Tottenham.
Needless to say after recent events in their penalty area, Man City would not baulk at keeper Artur Boruc, the outstanding Polish international.
"It is something that is out of our hands," said Pochettino about the clubs sniffing the attractive scents currently found in southern air.
"We cannot control or avoid other clubs being interested in our young players. We will do as much as we can to make sure they are here for a long time."
Comforting words. But alas, some way short of a panacea for "Pochettinotitus".
