Just one goal in his first ten top-flight outings this campaign had many doubting whether Dominic Calvert-Lewin's peak were behind him.
But, a mere four weeks on, he has become the most discussed forward in England after scoring 7 goals in 6 back-to-back games.
His newest goal, in a tie against Sunderland, elevated his season's haul to eight, establishing him as the top English scorer in the Premier League so far this season.
The 28-year-old moved to 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.
However, the statistics underpinning his comeback in Daniel Farke's new fast-breaking 3-5-2 formation are genuinely remarkable.
His six-match scoring run sees him in elite company as just the 11th English player to score in six or more straight Premier League matches.
To frame that statistic, even England captain Harry Kane did not achieve a run this long - his top is two separate five-match streaks.
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.
Why has Calvert-Lewin so hard to stop in recent weeks? A recent opponent's manager explained it perfectly.
"He has the ideal timing," the manager remarked. "He's smart and a excellent striker and he found the timing to arrive at the perfect moment."
That instinct and timing inside the 18-yard box was what made him a fan favourite at his previous club.
Experts highlight the system adjustment to a 3-5-2 as a key factor, enabling a greater number of players to enter the box and occupy defenders, thus provided the striker additional space.
"He is a classic centre-forward," noted a former professional. "For the goal... it was a neat little finish 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 character and I've persisted and kept going... I've believed in myself and this is the result."
His manager has voiced little astonishment at this hot streak, reiterating that the player is "among the elite strikers" in the division.
Calvert-Lewin's resurgence has inevitably fueled talks of an England return.
The ex- Sheffield United player has 11 England caps, with four goals, but has not featured for the national team since the last European Championship.
Pundits think the striker will be in consideration for the World Cup squad if he can maintain this level.
"He looks as in shape as he has in a long time," one said. "If he sustains this level of form... then he's going to be in a debate for a World Cup place."
Yet, the battle for places as backup to Harry Kane is intense.
Ollie Watkins of Aston Villa, coming off a match-winning two goals against Chelsea, is right now seen as in front in the hierarchy, according to some analysis.
"If you compare the two players, Watkins holds the advantage in terms of using his pace to stretch teams," it was noted.
"He also holds the advantage when it comes to making a significant impact at a major finals."
Ultimately, whether Calvert-Lewin is part of the squad may depend on how many specialist strikers the England manager decides to select.
"I think it might depend on whether the manager selects two or three centre-forwards," an pundit summarized. "If it is three, he certainly has a chance."
