17.22 – You’ve probably guessed from the starting line-up that Theo Walcott is being played as the central striker again for Arsenal.

The England international has impressed when playing in the role over the past few games.

17.38 – Artur Boruc has been handed a rare start today, but the goalkeeper flaps at a routine cross early on not once, but twice in two successive incidents

Expect Kelvin Davies to get the nod sooner than expected, if the Polish goalkeeper continues to look “a bundle of nerves,” as Sky commentator Alan Smith describes him.

18.27 – So half-time, and it’s been an interesting game to watch.

Despite being well below them in the table, the Saints have matched Arsenal in most departments and even bettered them in terms of possession for sections of that first half.

Their impressive performance is partially reflected by the scoreline, though they could have been even better off had they not conceded a sloppy goal on the brink of half-time.

Arsenal, similarly, were lacklustre in defence for their opponents’ goal, and will need to up their intensity after the break, or risk dropping points ultimately.

An additional intriguing facet of this game is the willingness of both sides to play attractive, attacking football – a rare enough situation in modern-day English football.

18.32 – We’re back underway…

18.36 – Here’s a look at that Do Prado own goal, replete with a suitably rubbish soundtrack.

18.59 – Walcott finds himself in a good position just outside the box, but shoots when he would have been better off crossing.

Failing to win here could see Chelsea extending the gap between them considerably, as they take on QPR tomorrow. In other words, the Gunners badly need a win here.

19.12 – And now Southampton’s other goalscorer (albeit in their own net), Do Prado, has been replaced by Steve De Ridder.

Meanwhile, the recently introduced Gervinho finds the side netting with a snapshot.

19.15 – Glorious chance for Puncheon, who finds himself free in the box.

However, his finish is disappointing, shooting straight at the goalkeeper.

The ineptitude of this Arsenal performance is highlighted by the fact that they’ve only had four shots on goal.

19.27 – So Arsenal’s winning run comes to an end, and deservedly so.

The Gunners looked off the pace for the most part, and the result could have been even worse for them had the Saints been a bit more clinical with their finishing.

Southampton can take pride in their performance, attacking at will when given the chance and rarely seeming in awe of their opponents, as some teams do when taking on Arsenal.

In addition, it’ll be interesting to see if Wenger persists with the Walcott-as-central-striker experiment in the next game, given its relative failure this evening.
