Nick Woltemade and Bruno Guimarães struck in the second half as Newcastle United earned a 2-0 win over Nottingham Forest, pilling more pressure on under-fire manager Ange Postecoglou.

The defeat extended Forest’s winless start under Postecoglou to seven games, with just one point from their opening four Premier League matches. With the club now sitting just above the relegation zone, scrutiny over the Australian’s future is set to dominate the international break.

After a tense first half at St James’ Park, Guimarães broke the deadlock with a curling effort from outside the box just before the hour mark. Forest players protested, claiming a foul by Guimarães on Morgan Gibbs-White in the build-up, but the goal stood after a VAR check.

Newcastle, who had been the league’s lowest scorers heading into the match, pressed for a second. Matz Sels denied Sandro Tonali and Malick Thiaw with smart saves, but he could do nothing to stop Woltemade’s thumping strike off the underside of the bar following a corner.

The Forest goalkeeper kept the scoreline respectable with further stops from Harvey Barnes, but Newcastle sealed the result in stoppage time. Woltemade calmly converted from the penalty spot after Guimarães was brought down by Elliot Anderson.

Postecoglou endured chants of “you’re getting sacked in the morning” from the home crowd as Newcastle celebrated their second league win of the campaign. Forest, meanwhile, remain mired in 17th and winless under their new boss, whose future looks increasingly uncertain.
