Just one goal in his first ten English top division games this season had plenty of questioning if Dominic Calvert-Lewin's best days were in the past.
But, a mere four weeks later, he has become the hottest striker in England after netting 7 goals in 6 back-to-back games.
His latest strike, in a stalemate against Sunderland, elevated his season's haul to eight, seeing him become the top English goalscorer in the Premier League this term.
The 28-year-old signed for Leeds United on a free transfer in the summer, after a nine-year period with Everton that was marred by injuries in its closing stages.
But, the data underpinning his revival in Daniel Farke's new fast-breaking 3-5-2 system are truly remarkable.
His six-match scoring run places him in exclusive company as just the 11th English player to score in six or more consecutive Premier League matches.
To provide context, even England captain Harry Kane did not achieve a run of this length - his top is two separate five-match runs.
And the only English striker to better Calvert-Lewin in the modern era is Jamie Vardy, who produced an eight-game scoring spree for Leicester City in 2019.
Why has Calvert-Lewin so difficult to stop in this period? A previous opponent's manager described it succinctly.
"He has the impeccable timing," the manager said. "He's clever and a genuinely top-class striker and he found the timing to arrive just on time."
That instinct and timing inside the 18-yard box was what turned him into a popular figure at his previous club.
Experts highlight the tactical shift to a 3-5-2 as a major factor, enabling more players to occupy the box and occupy defenders, thus given the striker additional space.
"He is a traditional 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 been through a lot since then. Lots of highs and lots of downs. 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 hot streak, stating again that the player is "one of the best strikers" in the competition.
Calvert-Lewin's scoring run has naturally fueled discussions of an England return.
The ex- Sheffield United player has eleven England appearances, netting four goals, but has not featured for the country since the last European Championship.
Observers think the striker will be in the mix for the World Cup squad if he can maintain this standard.
"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 conversation for a World Cup place."
But, the battle for places supporting Harry Kane is fierce.
Ollie Watkins of Aston Villa, fresh off a decisive two goals versus Chelsea, is currently seen as leading in the selection race, according to some analysis.
"If you compare the two players, Watkins holds the advantage in terms of using his pace to get behind teams," it was noted.
"He also holds the edge when it comes to making a significant impact at a major finals."
Finally, whether Calvert-Lewin will be the squad could hinge on how many specialist strikers the national team coach decides to select.
"I think it might hinge on whether he takes two or three centre-forwards," an expert summarized. "If it is three, he absolutely has a chance."
