A solitary goal in his initial ten top-flight games this campaign had numerous wondering whether Dominic Calvert-Lewin's peak were behind him.
However, a mere four weeks on, he stands as the most talked-about striker in England after scoring 7 goals in 6 consecutive games.
His latest goal, in a tie versus Sunderland, elevated his tally to eight, establishing him as the top English goalscorer in the Premier League so far this season.
The 28-year-old joined Leeds United on a Bosman move in the summer, following a nine-year stint with Everton that was blighted by setbacks in its latter stages.
However, the numbers behind his comeback in Daniel Farke's new counter-attacking 3-5-2 system are extremely remarkable.
His six-match scoring run places him in exclusive company as just the 11th English player to score in six or more straight Premier League outings.
To provide context, even England captain Harry Kane did not achieve a run of this length - his top remains two individual five-match streaks.
And the only English striker to better Calvert-Lewin in recent memory is Jamie Vardy, who went on an eight-game scoring spree for Leicester City in 2019.
What has made Calvert-Lewin so difficult to stop in recent weeks? A recent opponent's manager summed it up aptly.
"He has the impeccable timing," the manager stated. "He's clever and a excellent striker and he found the timing to arrive just on time."
That instinct and positional sense inside the penalty area was what made him a popular figure at his former team.
Analysts highlight the formation change to a 3-5-2 as a key factor, allowing a greater number of players to enter the box and occupy defenders, thereby provided the striker some extra space.
"He is a traditional centre-forward," observed a former professional. "For the goal... it was a lovely 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 test of mentality and I've persisted and kept going... I've believed in myself and here I am now."
His manager has voiced little astonishment at this hot streak, stating again that the player is "a top strikers" in the division.
Calvert-Lewin's resurgence has predictably ignited talks of an England call-up.
The ex- Sheffield United player has 11 England caps, scoring four goals, but has not played for the country since the last European Championship.
Analysts believe the striker will be in consideration for the World Cup squad if he can sustain this form.
"He looks as in shape as he has in a considerable period," one remarked. "If he sustains this level of form... then he's going to be in a debate for a World Cup place."
However, competition for places supporting Harry Kane is fierce.
Ollie Watkins of Aston Villa, following a decisive two goals versus Chelsea, is currently seen as in front in the pecking order, according to some analysis.
"If you look at the two players, Watkins has the advantage in terms of using his speed to test teams," it was said.
"He also has the edge when it comes to making a meaningful impact at a major finals."
Finally, whether Calvert-Lewin is part of the squad may depend on how many specialist strikers the head coach decides to select.
"I think it might depend on whether he takes two or three centre-forwards," an expert concluded. "If it is three, he definitely has a chance."
