Eddie Nketiah became the fifth player to score a hat-trick in the Premier League so far this season but who are the other four?
Arsenal thrashed Sheffield United 5-0 thanks to Eddie Nketiah's hat-trick, a Fabio Vieira penalty and Takehiro Tomiyasu's first-ever goal for the club.
Nketiah's hat-trick was the first scored by an Englishman for Arsenal in the Premier League since Theo Walcott put three goals past West Brom in 2015.
This also made Nketiah the fifth player to score a Premier League hat-trick this season but who are the other four?
5 players who have scored a Premier League hat-trick this season
Son Heung-Min
On September 2, Tottenham trashed Burnley 5-2 away from home, largely thanks to a hat-trick from Son at Turf Moor.
The South Korean superstar scored the equaliser in the 16th minute with a clever sink after Burnley had taken the lead.
Son's second goal was Tottenham's fourth in the 63rd minute after which he completed his hat-trick just three minutes later with a cool low finish when through one-on-one.
Evan Ferguson
On the same day as Son, Brighton's teenage centre-forward phenom, Evan Ferguson scored the second Premier League hat-trick of the season in a 3-1 win against Newcastle.
Ferguson's first was in the 27th minute after he capitalised on a mistake by Nick Pope to open the scoring.
The 18-year-old netted his second with a brilliant curler from outside the box in the 65th minute and then completed his hat-trick five minutes later thanks to a massive deflection to make it 3-0.
Although Newcastle pulled one back, Ferguson already became the fourth player 18 years old or under to score a Premier League hat-trick.
Erling Haaland
There's hardly any goalscoring list in the Premier League right now that wouldn't include Erling Haaland and he qualifies for this with his hat-trick against Fulham.
Manchester City beat Fulham 5-1 and Haaland's first goal made it 3-1 in the 58th minute.
It became 4-1 in the 70th minute when Haaland converted a penalty after which he rounded off the scoring in additional time.
Ollie Watkins
Aston Villa trashed Brighton 6-1 in the early kickoff on September 30 and the result was largely down to Ollie Watkins who scored an impressive hat-trick.
Watkins scored both of Aston Villa's first two goals with brilliant finishes in the 14th and 21st minutes.
His left-footed shot in the 65th minute deflected into the back of the net to complete what is only his second-ever Premier League hat-trick.
Eddie Nketiah
As earlier mentioned, it was the Eddie Nketiah show at the Emirates as he opened the scoring in the 28th minute after being picked out brilliantly by Declan Rice.
He then scored his and Arsenal's second just five minutes after halftime, pouncing on a loose ball from a corner kick to lash home.
His third was a thing of beauty, selling the hat-trick in style with a long-range belter in the 58th minute to make it 3-0.
