A solitary goal in his first ten top-flight games this season had numerous doubting whether Dominic Calvert-Lewin's peak were over.
However, a only four weeks afterwards, he stands as the most talked-about striker in England following bagging 7 goals in six consecutive games.
His newest finish, in a stalemate versus Sunderland, took his season's haul to eight, making him the leading English goalscorer in the Premier League so far this season.
The 28-year-old signed for Leeds United on a free transfer in the summer, following a nine-year spell with Everton that was blighted by setbacks in its closing stages.
Yet, the statistics behind his resurgence in Daniel Farke's new fast-breaking 3-5-2 setup are genuinely impressive.
His six-match scoring run puts him in elite 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 top is two individual five-match streaks.
And the only English striker to outdo Calvert-Lewin in the modern era is Jamie Vardy, who produced an eight-game scoring streak for Leicester City in 2019.
What is behind Calvert-Lewin so difficult to stop in this period? A previous opponent's manager described it aptly.
"He has the impeccable timing," the manager said. "He's intelligent and a really good striker and he found the timing to arrive just on time."
That instinct and positional sense inside the 18-yard box was what established him as a beloved player at his former team.
Experts point to the tactical shift to a 3-5-2 as a major factor, allowing a greater number of players to get into the box and occupy defenders, thereby created the striker some extra space.
"He is a classic centre-forward," commented a former professional. "For the goal... it was a exquisite little flick beyond the keeper, a typical centre-forward's goal."
"I've endured a lot since then. Lots of highs and lots of lows. A test of character and I've hung in there and kept going... I've believed in myself and here I am now."
His manager has voiced complete confidence at this rich vein of form, reiterating that the player is "a top strikers" in the division.
Calvert-Lewin's return to form has inevitably sparked conversations of an England recall.
The former Sheffield United player has eleven England appearances, scoring four goals, but has not played for the country since the most recent European Championship.
Pundits think the striker will be in contention for the World Cup squad if he can sustain this level.
"He looks as in shape as he has in a long time," one commented. "If he maintains this level of form... then he's going to be in a conversation for a World Cup place."
But, the battle for places behind Harry Kane is intense.
Ollie Watkins of Aston Villa, following a decisive two goals versus Chelsea, is currently considered to be leading in the hierarchy, according to some analysis.
"If you contrast the two players, Watkins possesses the edge in terms of using his pace to stretch teams," it was said.
"He also holds the advantage when it comes to making a decisive impact at a major tournament."
Ultimately, whether Calvert-Lewin will be the squad may depend on how many natural strikers the England manager decides to take.
"I think it might come down to whether the manager selects two or three centre-forwards," an pundit added. "If it is three, he absolutely has a chance."
