Republic of Ireland forward Michael Obafemi created a goal on his first Premier League start but Southampton let a two-goal lead slip to draw 2-2 with Manchester United.
United wasted a glorious early opening and were punished for their profligacy in the 13th minute when the 18-year-old's clever lay-off opened up the space for Stuart Armstrong to send a bullet of a shot past David de Gea,
It was Armstrong's third goal in a week.
A makeshift United defence, including young midfielder Scott McTominay, continued to look vulnerable and soon enough it was two, with Cedric Soares curling a sublime free kick into the net with 20 minutes on the clock.
No Premier League side has dropped more points from winning positions than Southampton this season, though, and United were back in it in the 33rd minute through Romelu Lukaku, who ended a run of 12 games without a goal for United in all competitions as he dispatched Marcus Rashford's through ball past Alex McCarthy
Six minutes later and Southampton were breached once again as Ander Herrera drew United level with a fine flicked finish, Rashford again the provider.
Southampton had the better of the second half and there was disappointment for Obafemi just after the hour when he was forced off with what looked like a hamstring injury, though not until he had a penalty claim denied when McTominay made no contact with the ball.
David de Gea was forced into a smart late save to preserve a point for United, who are now six points behind fourth-placed Chelsea and 16 points behind leaders Manchester City, while Southampton stayed in the bottom three and remained winless at home.
