Victor Wanyama's first Premier League goal was the difference between Southampton and Swansea on Saturday, with his 79th minute strike ensuring that the Saints went second in the table with victory.
The midfielder, who had joined the action only ten minutes before the goal as a replacement for James Ward-Prowse, smashed an effort into the top left-hand corner from just inside the penalty area, following Graziano Pelle's neat pass.
The victory took Ronald Koeman's side up to second in the Barclays Premier League following an impressive opening to the campaign; a start that has seen early season predictions for relegation firmly thrown out the window.
In a very even first half, neither side dominated for the majority, but it was the Swans who had the edge in terms chances created. Wayne Routledge saw an effort come back off the crossbar and Gylfi Sigurdsson tested Fraser Forster from long range.
Wilfried Bony and Jose Fonte went into the referee's notebook shortly after as tempers flared and on the stroke of half-time came two more incidents which would shape the second 45.
First, Bony had a header cleared off the line by Ryan Bertrand, before his lunge on Maya Yoshida saw him receive a second yellow card and his marching orders, with the Japanese defender being replaced at the break through injury.
Man advantage counts
With the extra man on their side, the visitors attacked the travelling fans in the second-half and took control of the game, keeping possession for long periods to assert their control.
Dusan Tadic saw an effort loop over the bar before Pelle had two headers saved by Lukasz Fabianksi but the pivotal moment was yet to come.
After Ward-Prowse became the second Saint whose afternoon was ended prematurely through injury, Wanyama took his place with 20 minutes left to play.
It was a switch that paid dividends for Koeman, and after Pelle found Wanyama surging into the box, the ball sat perfectly for the Kenyan to rifle into the far corner to send the travelling fans wild.
The Saints spent the last ten minutes in control, keeping the ball and again using the man advantage to their benefit. The final whistle went and the three points headed back to the South coast, leaving Southampton to taste the dizzy heights of second in the Premier League.
