A solitary goal in his first ten English top division outings this campaign had plenty of questioning if Dominic Calvert-Lewin's prime were over.
Yet, a just four weeks later, he is the most talked-about striker in England after scoring seven goals in six back-to-back games.
His most recent goal, in a stalemate versus Sunderland, took his total to eight, making him the highest English scorer in the Premier League this campaign.
The 28-year-old moved to Leeds United on a free transfer in the summer, following a nine-year stint with Everton that was blighted by fitness issues in its latter stages.
However, the data behind his resurgence in Daniel Farke's new fast-breaking 3-5-2 formation are genuinely impressive.
His six-game scoring run puts him in prestigious company as just the 11th English player to score in six or more consecutive Premier League outings.
To put that into perspective, even England captain Harry Kane never managed a run lasting this many games - his best remains two separate five-match streaks.
And the sole English striker to outdo Calvert-Lewin in recent memory is Jamie Vardy, who went on an eight-game scoring run for Leicester City in 2019.
Why has Calvert-Lewin so difficult to stop in this period? A recent opponent's manager summed it up aptly.
"He has the perfect timing," the manager stated. "He's intelligent and a genuinely top-class striker and he found the timing to arrive exactly when needed."
That instinct and positional sense inside the penalty area was what turned him into a beloved player at his former team.
Analysts highlight the tactical shift to a 3-5-2 as a major factor, helping more players to occupy the box and occupy defenders, thus given the striker some extra space.
"He is a classic centre-forward," observed a former professional. "For the goal... it was a exquisite little touch beyond the keeper, a typical centre-forward's goal."
"I've endured a lot since then. Lots of highs and lots of lows. A challenge of mentality and I've hung in there and kept going... I've believed in myself and here I am now."
His manager has expressed complete confidence at this rich vein of form, emphasizing that the player is "among the elite strikers" in the division.
Calvert-Lewin's return to form has predictably ignited discussions of an England recall.
The ex- Sheffield United player has eleven England caps, with four goals, but has not featured for the national team since the previous European Championship.
Analysts think the striker will be in consideration for the World Cup squad if he can maintain this form.
"He looks as in shape as he has in a considerable period," one commented. "If he continues this level of form... then he's going to be in a discussion for a World Cup place."
But, competition for places as backup to Harry Kane is fierce.
Ollie Watkins of Aston Villa, fresh off a decisive brace versus Chelsea, is right now seen as ahead in the selection race, according to some analysis.
"If you contrast the two players, Watkins has the advantage in terms of using his speed to stretch teams," it was stated.
"He also holds the edge when it comes to making a decisive impact at a big competition."
Finally, whether Calvert-Lewin will be the squad might come down to how many natural strikers the head coach decides to select.
"I think it might hinge on whether the manager includes two or three centre-forwards," an analyst summarized. "If it is three, he certainly has a chance."
