Newcastle United 0-1 Arsenal
Steve Bruce was handed a defeat in his first game in charge of Newcastle United as Arsenal edged a 1-0 victory at St James' Park.
New Magpies boss Bruce handed a full debut to record signing Joelinton, who started as the lone attacker in a 3-5-1-1 formation which saw Miguel Almiron acting as the main support to the Brazilian.
Gunners head coach Unai Emery left new signings David Luiz, Gabriel Martinelli, Dani Ceballos and Nicolas Pepe on the bench, with both Reiss Nelson and Joe Willock handed starts.
Possession football was the name of the game in the opening stages of the clash on Tyneside, with neither goalkeeper troubled in the opening ten minutes.
Shouts went up for a penalty with almost 20 minutes played, but Almiron was shown a yellow card for simulation, rather than winning a spot-kick.
Soon after Jonjo Shelvey smacked a shot against a post from just outside the area as the hosts began to gain the upper hand, before Joelinton belted an effort straight at keeper Bernd Leno.
Pierre-Emerick Aubameyang became the first Gunners player to test Martin Dubravka with just over half an hour played and there were no further openings before the half-time whistle sounded.
The early stages of the second half proved little more entertaining than the first, but that all changed when Aubameyang struck to give the visitors the lead just before the hour mark.
Magpies substitute Jetro Willems lost the ball to Ainsley Maitland-Niles and his astute pass allowed Aubameyang the opportunity to beat the stranded Dubravka.
Record signing Nicolas Pepe entered the fray for the visitors 19 minutes from time, before the hosts mounted a late charge, with Allan Saint-Maximin and Joelinton having chances.
However, they were unable to find a way through as Bruce suffered a loss at the start of his Magpies reign.
