Pierre-Emerick Aubameyang hit a personal milestone as his first Premier League hat-trick saw Arsenal past Leeds United on Sunday.
Aubameyang and Hector Bellerin put Arsenal 4-0 up by the 47th minute at Emirates Stadium, though Leeds did strike back twice to make things a little more uncomfortable for Mikel Arteta's side.
That match followed on from Wolves beating Southampton in the day's early kick-off, and West Brom holding Manchester United to a 1-1 draw – Bruno Fernandes' stunner earning the Red Devils a point.
In the late game, lowly Fulham picked up a much-needed win by seeing off a lacklustre Everton 2-0 at Goodison Park.
ARSENAL 4-2 LEEDS UNITED: DOUBLE CENTURY UP FOR AUBA
On his first league start since January 18, Aubameyang was in sparkling form against Leeds.
Having opened the scoring after 13 minutes, Aubameyang netted from the penalty spot shortly before half-time, bringing up his 200th goal across Europe's "top five" leagues.
It was the 31-year-old's 369th appearance across spells at Lille (two goals), Monaco (two), Saint-Etienne (37), Borussia Dortmund (98) and Arsenal (62).
Since his Ligue 1 debut in 2009, he is one of just nine players to score 200 or more goals across the continent's five leading divisions.
Arsenal scored four (or more) goals at the Emirates for the first time in the Premier League this season, having last done so in a 4-0 win over Norwich City in July of last year.
Leeds, meanwhile, have won just one of their last 24 away league games in London (D6 L17), losing all four such matches this season by an aggregate 14-4 score, and the Whites remain without a win in nine meetings with Arsenal in all competitions (D2 L7).
Aubameyang was also the third player in Premier League history to score a hat-trick on Valentine's Day, after Matt Le Tissier vs Liverpool in 1994 and Michael Owen vs Sheffield Wednesday in 1998.
WEST BROM 1-1 MANCHESTER UNITED: MORE BRUNO BRILLIANCE SAVES LACKLUSTRE RED DEVILS
The Red Devils' only win from their previous five top-flight matches was the 9-0 hammering of Southampton at Old Trafford (D3 L1), while the Baggies have just one win in 11 under Sam Allardyce and have conceded nine more goals than any other team since his first game at the helm.
The ever-reliable Fernandes scored United's leveller just before half-time at the Hawthorns, with the Red Devils now recovering 22 points from losing positions this term – 10 more than any other team.
The Portuguese playmaker has 38 goal involvements in as many games for United – the only player with more in their opening 38 in Premier League history is Andrew Cole (46 in 1993-94 for Newcastle United).
West Brom's goal was scored after just 83 seconds by Mbaye Diagne – the earliest conceded by United in a Premier League game since Christian Eriksen's 11-second strike for Spurs in January 2018. He is the 12th different Senegalese player to score under Allardyce.
United full-back Luke Shaw has five league assists for the season, the most he has managed in a single campaign – he only had seven in total prior to the start of this season.
Ole Gunnar Solskjaer's side are unbeaten in all 12 away Premier League matches this season (W8 D4), only the fourth time a team has avoided defeat in their first 12 away Premier League games of a season: Arsenal in 2001-02 and 2003-04, and Liverpool in 2019-20, all of whom went on to win the title.
SOUTHAMPTON 1-2 WOLVES: SAINTS MARCH INTO CLUB-RECORD WORST RUN
It has been a miserable time for Southampton recently with Sunday's defeat to Wolves at St Mary's settled by second-half goals from Ruben Neves and Pedro Neto, which cancelled out Danny Ings' 25th-minute opener.
The Saints have now lost six consecutive league matches for the first time in their history, while they have led in each of their last four top-flight matches against Wolves without winning any of them (D2 L2), resulting in 10 points lost – the most points one side have dropped against another since the start of last season.
Only Liverpool (14) and Manchester United (12) have won more Premier League matches after going behind than Wolves' 10 since the start of 2018-19.
Meanwhile, winger Neto has been directly involved in nine Premier League goals this season (five goals and four assists), which represents the most of any under-21 player in the competition this campaign.
On the opposition side, Ings is one of only four players to score 30 Premier League goals since the start of last season, along with Mohamed Salah (36), Jamie Vardy (35) and Harry Kane (31).
EVERTON 0-2 FULHAM: MAJA MAGIC BOOSTS COTTAGERS
It was a first Premier League start to remember for Josh Maja, who is the second-youngest player to score on his full debut for Fulham in the competition, after Collins John versus Blackburn Rovers in April 2004 (18y 178d).
Maja is also the first Nigerian to mark his first Premier League start with a brace since Efan Ekoku for Norwich City back in May 1993 (v Middlesbrough).
It helped Fulham pick up their first-ever away win at Everton in league competition, on what was their 28th attempt. Coming into the game, they had lost each of their last 22 away league games against the Toffees.
The Cottagers consequently have a first Premier League victory since November, ending a run of 12 games without a win in the competition.
Everton have now lost three of their last four Premier League games at Goodison Park (D1), as many defeats as they suffered in Carlo Ancelotti's first 17 home games in charge in the competition (W8 D6).
