Newcastle came out unchanged after a promising first half. Although it was all Arsenal to start the second half.
The Gunners pushed from the start and created a few chances as they dominated possession. It looked only a matter of time for Arsenal to find their breakthrough.
That came in the 53rd minute when Nicolas Pepe launched a cross from the right, which Pierre-Emerick Aubemayang headed past Dubravka into the far corner.
The defending was poor as neither Valentino Lazaro or Federico Fernandez jumped to contest Aubemanyang’s header.
The Gunners made it 2-0 less than three minutes later when Bukayo Saka nutmegged Lazaro on the left and crossed to an unmarked Nicolas Pepe in the box. He easily beat Dubravka with his shot.
Newcastle were thoroughly dominated in the opening 15 minutes of the second half. They did manage a chance to get one back in the 62nd minute when Allan Saint-Maximin found Ciaran Clark in the box. The 30-year-old should have put it away, but instead, it was slightly deflected wide for a corner.
In the 73rd minute, Bruce went to his bench and brought Isaac Hayden and Matt Ritchie on for Lazaro and Fernandez. It was a struggle defensively for Valentino in the second half.
The Magpies transitioned to a back four with Isaac Hayden at right-back. Ritchie looked to be playing centrally alongside Sean Longstaff with Bentaleb sitting deeper.
Newcastle again almost halved the difference as Allan Saint-Maximin turned in the box and launched an effort that struck the post.
Ciaran Clark was forced off in the 83rd minute after a bruising challenge on Sako. Fabian Schar came on to partner Jamaal Lascelles at the back. We hope Clark will be ok, but he looked to really have turned his ankle.
Arsenal scored again when a Lacazette effort deflected to Mezut Ozil in front of goal. His shot was rather tame, but Martin Dubravka couldn’t handle it as it went under him. It was poor from Newcastle on all accounts.
They added the final goal late in stoppage time. This time it was Alexandre Lacazette who was teed up by Pepe and left unmarked in the box. The Frenchman easily beat Dubravka.
There were signs that this team had turned a corner in the first half. However, we were thoroughly dominated by Arsenal after the break. We again seem to struggle with a plan B when things start to go awry.
Our defense were unexpectedly awful in the second half to go with our toothless attack. It is an evening to forget after some positives in the opening forty-five minutes.
