Arsenal bounced back from a disappointing EFL Cup defeat in midweek with an emphatic 5-1 win over West Ham on Saturday.
And, with a brilliant 14-minute hattrick, it was Alexis Sanches who was, once again, the difference maker for the Gunners.
All three of the Chilean's goals were impressive but it was his third and final effort - a dinked finish after a step over - that was the pick of the bunch. It left everyone from Arsenal fans to Gary Lineker in awe. That includes the West Ham ball boy behind the goal.
Sanchez's finish was understandably one of the topics for debate on last night's Match of the Day, with both Lineker and the Premier League's all-time record goalscorer, Alan Shearer, full of praise for the ingenious bit of skill before the goal itself.
But, whilst pundits and fans of Twitter have tried their best to describe just what a well taken goal it was, sometimes actions speak louder than words.
And, thanks to one angle of the goal shown on Match of the Day, that is the case here after the camera captured the look of pure shock on the Hammers ball boy's face as he sat behind the goal and watched Sanchez complete his hattrick in style.
Frozen still with his mouth wide open - the lad's reaction sums up the goal pretty well we'd say.
It was an impressive day all around for Sanchez who also provided an assist for Mesut Ozil's opener in the 23rd minute.
The 27-year-old now has 11 goals and four assists in the Premier League so far, to add to two goals and two assists in Arsenal's Champions League campaign.
He has found a new gear since moving into a more central position for Arsene Wenger's side this season and, speaking after the game, his manager talked up Sanchez's ability to become one of the world's best strikers.
"I think he likes the position," Wenger said, via Sky Sports. "When it comes off and he walks off with the ball under his arm it's a good feeling and I hope there is more to come.
"The leading strikers in world football at the moment are South American. He has all the ingredients to be a top class striker and he showed that again."
