A solitary goal in his first ten English top division outings this season had plenty of doubting whether Dominic Calvert-Lewin's prime were behind him.
However, a mere four weeks afterwards, he has become the most talked-about striker in England after bagging seven goals in six back-to-back games.
His most recent finish, in a tie versus Sunderland, brought his season's haul to eight, establishing him as the top English scorer in the Premier League this term.
The 28-year-old moved to Leeds United on a Bosman move in the summer, after a nine-year period with Everton that was blighted by fitness issues in its closing stages.
But, the numbers underpinning his revival in Daniel Farke's new counter-attacking 3-5-2 formation are extremely remarkable.
His six-game scoring streak sees him in elite 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 lasting this many games - his longest remains two individual five-match runs.
And the sole English striker to better Calvert-Lewin in recent years is Jamie Vardy, who embarked on an eight-game scoring streak for Leicester City in 2019.
What is behind Calvert-Lewin so tough to stop in this period? A recent opponent's manager summed it up perfectly.
"He has the impeccable timing," the manager remarked. "He's clever and a excellent striker and he found the timing to arrive at the perfect moment."
That nose for goal and positional sense inside the 18-yard box was what made him a popular figure at his previous club.
Analysts highlight the system adjustment to a 3-5-2 as a key factor, enabling a greater number of players to get into the box and occupy defenders, which has given the striker additional space.
"He is a archetypal centre-forward," noted a former professional. "For the goal... it was a neat little flick beyond the keeper, a textbook centre-forward's goal."
"I've endured a lot since then. Lots of ups and lots of lows. A challenge of resolve and I've persisted and kept going... I've had faith and this is the result."
His manager has voiced little astonishment at this hot streak, reiterating that the player is "one of the best strikers" in the competition.
Calvert-Lewin's return to form has naturally fueled talks of an England return.
The ex- Sheffield United player has eleven England appearances, scoring four goals, but has not featured for the Three Lions since the previous European Championship.
Observers think the striker will be in contention for the World Cup squad if he can sustain this form.
"He looks as in shape as he has in a long time," one commented. "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 supporting Harry Kane is intense.
Ollie Watkins of Aston Villa, fresh off a match-winning brace against Chelsea, is presently regarded as ahead in the hierarchy, 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 possesses 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 out-and-out strikers the England manager decides to select.
"I think it might depend on whether he takes two or three centre-forwards," an pundit concluded. "If it is three, he certainly has a chance."
