Newcastle took the lead from a corner as Kieran Trippier’s delivery was turned in by Brighton’s Deniz Undav. On the stroke of half-time, The Magpies doubled their lead from another set-piece as Dan Burn headed in Trippier’s delivery against his former club.
Shortly after the restart, Undav made amends for his own goal by pulling one back for Brighton. And as Brighton pushed for an equaliser in the closing stages, Callum Wilson beat the offside trap and slotted home his 18th goal of the season.
And 3-1 soon became 4-1 as Wilson set-up Bruno Guimaraes to put the result beyond doubt in stoppage time.
The win takes Newcastle four points inside the top four with two games remaining. Next up in Leicester City on Monday night where a win would guarantee Champions League football for next season.

11. Callum Wilson - 7
The ball just didn’t quite drop for him in the penalty area for the majority of the game but did well to beat the offside trap and slot home his 18th of the season. Did well to set up Guimaraes for the fourth goal with some unselfish play but could have scored another shortly after. | Getty Images
