A solitary goal in his first ten English top division games this campaign had numerous wondering if Dominic Calvert-Lewin's peak were in the past.
However, a mere four weeks on, he stands as the most discussed attacker in England following bagging 7 goals in 6 back-to-back games.
His newest strike, in a stalemate versus Sunderland, took his tally to eight, making him the leading English goalscorer in the Premier League so far this season.
The 28-year-old joined Leeds United on a Bosman move in the summer, after a nine-year stint with Everton that was hampered by injuries in its latter stages.
However, the data behind his resurgence in Daniel Farke's new fast-breaking 3-5-2 setup are truly remarkable.
His six-game scoring sequence places him in prestigious company as just the 11th English player to score in six or more straight Premier League matches.
To provide context, even England captain Harry Kane did not achieve a run lasting this many games - his best remains two separate five-match runs.
And the only English striker to better Calvert-Lewin in the modern era is Jamie Vardy, who embarked on an eight-game scoring run for Leicester City in 2019.
What is behind Calvert-Lewin so tough to stop in recent weeks? A latest opponent's manager described it perfectly.
"He has the impeccable timing," the manager remarked. "He's smart and a really good striker and he found the timing to arrive at the perfect moment."
That natural ability and positional sense inside the 18-yard box was what established him as a fan favourite at his previous club.
Analysts highlight the system adjustment to a 3-5-2 as a significant factor, allowing more players to occupy the box and occupy defenders, thereby created the striker additional space.
"He is a classic centre-forward," commented a former professional. "For the goal... it was a neat little touch beyond the keeper, a typical centre-forward's goal."
"I've been through a lot since then. Lots of highs and lots of lows. A challenge of resolve and I've persisted and kept going... I've backed myself and this is the result."
His manager has voiced complete confidence at this rich vein of form, reiterating that the player is "one of the best strikers" in the division.
Calvert-Lewin's return to form has predictably sparked conversations of an England return.
The former Sheffield United player has eleven England appearances, with four goals, but has not represented the country since the previous European Championship.
Observers think the striker will be in the mix for the World Cup squad if he can maintain this standard.
"He looks as in shape as he has in a long time," one remarked. "If he maintains this level of form... then he's going to be in a debate for a World Cup place."
However, the battle for places as backup to Harry Kane is fierce.
Ollie Watkins of Aston Villa, following a decisive brace versus Chelsea, is currently seen as in front in the selection race, according to some analysis.
"If you contrast the two players, Watkins has the advantage in terms of using his pace to test teams," it was stated.
"He also has the advantage when it comes to making a decisive impact at a major finals."
In the end, whether Calvert-Lewin makes it to the squad could hinge on how many natural strikers the head coach decides to include.
"I think it might hinge on whether he includes two or three centre-forwards," an expert summarized. "If it is three, he definitely has a chance."
