1 thing helped Arsenal curb-stomp PSV

Arsenal obliterated PSV in the Champions League, and one thing allowed Mikel Arteta's side to romp to a convincing win.

To say that Arsenal's 7-1 win over PSV in the Champions League was a surprise would be the understatement of the century.

After back-to-back weeks of being shut out, the Gunners' new-look forward line wasn't exactly flowing with confidence entering the PSV clash, but we have talked about all the team needing was one goal, and maybe that would get the party started.

And boy did it.

In 30 crisp minutes, the Gunners were 3-0 up and cruising, signaling at least for the night that the goal-scoring woes that have plagued the team since Kai Havertz went down with injury might have been forgotten.

But what was the catalyst for the Gunners, who in their previous five games, has scored a total of seven goals, to then score seven in 90 minutes of football?

Arsenal's goal-scoring return down to one thing vs. PSV

Was it mental? Or something else?

For Arteta, it was all down to execution in the final third.

"That’s what we want, but at the end, it’s a thing of execution," Arteta said via arsenal.com. "Willingness is for sure going to be there, execution is something else."

Is Arteta right? Is that all it really was?

The Gunners had 15 shots on PSV's goal, and eight of them were on target, which is a far cry from the past two outings.

With Arsenal never short on creating chances, it was the taking of them that had been its Achilles heel, and against PSV, once Jurrien Timber's header went in, it was like the mental handbrake had been released.

Then others got in on the act with Ethan Nwaneri, Mikel Merino, Leandro Trossard and a Martin Odegaard double capping off what was a superb night for the Gunners.

Now the squad knows it can do it in front of goal, instead of hoping it can do it, and while that might seem like a trivial thing, professional sports is 90 percent above the shoulders, and maybe this Champions League outing is the catalyst for Arsenal to finish the year with a flurry.

Up next is Manchester United at Old Trafford and the last thing Arteta will want is for his team to go to water in front of goal against their rivals.

But as usual, the difference between winning and losing is down to one thing - execution.
