Guimaraes is mobbed as he makes his way off the bench, having scored the winner for Newcastle on his full debut against Southampton.
That is nine unbeaten now for the Magpies, who trailed to Stuart Armstrong’s goal but equalised through Wood before half-time.
Southampton will feel they were the better side throughout but had no answer to Guimaraes’ sublime volley.
Southampton (4-4-2): Fraser Forster;
Valentino Livramento, Jan Bednarek, Mohammed Salisu, Kyle Walker-Peters;
Stuart Armstrong, James Ward-Prowse, Oriol Romeu; Mohamed Elyounoussi;
Che Adams, Armando Broja.
Subs: Willy Caballero, Jack Stephens, Shane Long, Adam Armstrong, Romain Perraud,
Moussa Djenepo, Will Smallbone, Ibrahima Diallo, Yan Valery.
Newcastle United (4-3-3): Martin Dubravka;
Emil Krafth, Fabian Schar, Dan Burn, Matt Targett;
Joe Willock, Jonjo Shelvey, Bruno Guimaraes;
Jacob Murphy, Chris Wood, Ryan Fraser.
Subs: Karl Darlow, Paul Dummett, Jamaal Lascelles, Matt Ritchie, Javier Manquillo, Miguel Almiron, Dwight Gayle, Sean Longstaff, Lucas De Bolle.
Southampton lead through a very scrappy Armstrong goal! Walker-Peters’ cross to the far post is nodded back across goal by a combination of Elyounoussi and Broja, reaching Armstrong. His header is tame but hits Burn, who attempts to block, and drops into the bottom corner. 1-0.
It’s 1-1! Newcastle’s first moment of real quality provides an equaliser and the first goal in black and white for January signing Wood. Newcastle has a couple of opportunities to cross from the left and eventually do through Shelvey, whose gorgeous ball beats Salisu and lands on the head of Wood. He makes no mistake, with Forster rooted to his spot.
It’s Guimaraes! The £35m man marks his full debut with a goal! And what a goal. Burn nods Targett’s deep corner back across goal for Guimaraes to aim a backheeled volley high past, Forster. 2-1 Newcastle.
So, what’s next for Newcastle United and Southampton?
Results elsewhere have gone Newcastle’s way, too, with Norwich City and Watford beaten and Leeds United losing, so Howe must feel they are close to securing safety now. The gap to 18th-placed Burnley is 10 points, while they are only four behind Southampton in the top half.
Southampton will hope to bounce back from consecutive defeats at home to Watford on Sunday when Newcastle are at Chelsea.
