A solitary goal in his initial ten top-flight appearances this season had plenty of doubting whether Dominic Calvert-Lewin's peak were in the past.
Yet, a only four weeks later, he has become the most talked-about attacker in England following netting seven goals in 6 consecutive games.
His newest finish, in a tie against Sunderland, brought his total to eight, establishing him as the leading English scorer in the Premier League so far this season.
The 28-year-old joined Leeds United on a free transfer in the summer, following a nine-year spell with Everton that was marred by setbacks in its final stages.
However, the data underpinning his comeback in Daniel Farke's new fast-breaking 3-5-2 setup are extremely notable.
His six-game scoring sequence sees him in prestigious company as only the 11th English player to score in six or more straight Premier League fixtures.
To provide context, even England captain Harry Kane never managed a run this long - his best remains two separate five-match runs.
And the sole English striker to outdo Calvert-Lewin in recent years 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 this period? A recent opponent's manager described it aptly.
"He has the perfect timing," the manager said. "He's intelligent and a excellent striker and he found the timing to arrive at the perfect moment."
That nose for goal and timing inside the 18-yard box was what made him a popular figure at his previous club.
Analysts highlight the tactical shift to a 3-5-2 as a major factor, enabling a greater number of players to occupy the box and occupy defenders, thus provided the striker some extra space.
"He is a archetypal centre-forward," noted a former professional. "For the goal... it was a lovely little flick beyond the keeper, a classic centre-forward's goal."
"I've endured a lot since then. Lots of ups and lots of lows. A test of resolve and I've persevered and kept going... I've believed in myself and now I'm reaping the rewards."
His manager has voiced little astonishment at this hot streak, emphasizing that the player is "one of the best strikers" in the league.
Calvert-Lewin's resurgence has inevitably sparked discussions of an England return.
The ex- Sheffield United player has 11 England appearances, with four goals, but has not played for the national team since the previous European Championship.
Analysts feel the striker will be in consideration for the World Cup squad if he can maintain this form.
"He looks as sharp as he has in a while," one said. "If he continues this level of form... then he's going to be in a discussion for a World Cup place."
Yet, competition for places behind Harry Kane is fierce.
Ollie Watkins of Aston Villa, following a decisive two goals against Chelsea, is currently considered to be ahead in the selection race, according to some analysis.
"If you compare the two players, Watkins possesses the edge in terms of using his speed to stretch teams," it was stated.
"He also has the edge when it comes to making a decisive impact at a big competition."
Finally, whether Calvert-Lewin is part of the squad could hinge on how many specialist strikers the England manager decides to take.
"I think it might come down to whether he selects two or three centre-forwards," an expert concluded. "If it is three, he definitely has a chance."
