Only one goal in his initial ten top-flight games this campaign had numerous doubting whether Dominic Calvert-Lewin's peak were over.
But, a mere four weeks later, he has become the most discussed attacker in England following bagging seven goals in 6 back-to-back games.
His latest goal, in a tie against Sunderland, elevated his total to eight, establishing him as the leading English goalscorer 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 marred by setbacks in its final stages.
But, the data behind his comeback in Daniel Farke's new fast-breaking 3-5-2 formation are extremely notable.
His six-match scoring sequence sees him in exclusive company as just the 11th English player to score in six or more successive Premier League outings.
To put that into perspective, even England captain Harry Kane never managed a run of this length - his longest 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 difficult to stop in recent weeks? A recent opponent's manager summed it up aptly.
"He has the impeccable timing," the manager said. "He's intelligent and a genuinely top-class striker and he found the timing to arrive just on time."
That instinct and timing inside the box was what established him as a beloved player at his previous club.
Analysts point to the formation change to a 3-5-2 as a major factor, allowing a greater number of players to enter the box and occupy defenders, thereby provided the striker a little more space.
"He is a archetypal centre-forward," observed a former professional. "For the goal... it was a lovely little finish 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 character and I've persevered and kept going... I've believed in myself and now I'm reaping the rewards."
His manager has expressed complete confidence at this hot streak, reiterating that the player is "a top strikers" in the competition.
Calvert-Lewin's resurgence has naturally fueled discussions of an England recall.
The ex- Sheffield United player has eleven England caps, netting four goals, but has not featured for the country since the most recent European Championship.
Analysts believe the striker will be in the mix for the World Cup squad if he can sustain this form.
"He looks as sharp as he has in a considerable period," 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 intense.
Ollie Watkins of Aston Villa, following a decisive double against Chelsea, is presently seen as leading in the hierarchy, according to some analysis.
"If you contrast the two players, Watkins holds the edge in terms of using his speed to get behind teams," it was noted.
"He also possesses the advantage when it comes to making a significant impact at a major tournament."
Ultimately, whether Calvert-Lewin makes it to the squad may depend on how many specialist strikers the head coach decides to take.
"I think it might hinge on whether he takes two or three centre-forwards," an pundit added. "If it is three, he absolutely has a chance."
