Jurriën Timber and William Saliba scored from corners to give Arsenal a 2-0 victory over Manchester United at the Emirates Stadium on Wednesday, cutting the gap to Premier League leaders Liverpool and ending Ruben Amorim's unbeaten start.

The Gunners threatened from set pieces but little else in a strangely subdued first half, with Thomas Partey unable to direct a dangerous Declan Rice corner that injured defender Gabriel may well have converted.

United goalkeeper André Onana twice needed to punch clear from corners, with the second presenting a half-chance for Gabriel Martinelli who sliced his shot high and wide.

The visitors were content to slow the game down and retain possession, but went close before the break as Diogo Dalot dragged his effort wide from a tight angle.

Arsenal were sharper after the restart and took the lead from another Rice corner in the 54th minute, with Timber heading in from a tight angle.

United nearly levelled from a set piece of their own shortly after, but David Raya produced a superb fingertip save at full stretch to claw away Matthijs de Ligt's goalbound header.

Arsenal put the game to bed in the 73rd minute when Partey's header from a Bukayo Saka delivery bounced off Saliba and in for Arsenal's 22nd league goal from a corner since the start of last season.

Rice nearly added a third before substitute Mikel Merino headed past the post from the resulting corner, as each set piece generated a roar of expectation.

Arsenal saw the game out to capitalise on Liverpool's draw at Newcastle United, with the victory putting them third behind Chelsea on goal difference on 28 points from 14 games -- with the gap to the leaders now seven points.

Amorim's first loss as United manager -- and his first league defeat since his former club Sporting were beaten by Vitória de Guimaraes in December 2023 -- left them 11th on 19 points.
