Newcastle United secured a 1-0 victory over newly-promoted Southampton in their Premier League opener at St James' Park, despite playing with 10 men for more than an hour after Fabian Schar was sent off for headbutting Ben Brereton Diaz. Joelinton's goal, stemming from a goalkeeper error by Alex McCarthy, came just before half-time. Southampton, who had a Jack Stephens goal disallowed for offside, dominated much of the match but failed to capitalize on their numerical advantage. Newcastle's defense, bolstered by a high press and timely interceptions, held firm to secure the win. This result highlighted Newcastle's need for defensive reinforcements as they look to improve in the coming matches.
