Joelinton missed a glorious chance earlier in this half, but no-one will mind now as he scores to the delight of the Newcastle fans.
It's a brilliant move down the right wing and the low cross from Alexander Isak is perfect for Joelinton and this time he doesn't miss from close range and the visitors lead.
At the moment Southampton are in control of this game and Nathan Jones will be a very happy manager, but they need to capitalise on this possession.
Kieran Trippier sees yellow, striding in for challenge but Samuel Edozie is too fast, got their first and the England man gets a yellow card.
