Only one goal in his initial ten English top division appearances this campaign had many questioning whether Dominic Calvert-Lewin's best days were over.
But, a mere four weeks later, he stands as the hottest attacker in England after netting 7 goals in six consecutive games.
His most recent goal, in a 1-1 draw against Sunderland, brought his total to eight, seeing him become the leading 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 setbacks in its closing stages.
Yet, the data supporting his revival in Daniel Farke's new fast-breaking 3-5-2 system are truly notable.
His six-match scoring sequence puts him in exclusive company as only the 11th English player to score in six or more straight Premier League outings.
To frame that statistic, even England captain Harry Kane did not achieve a run this long - his best remains two distinct five-match streaks.
And the sole English striker to better Calvert-Lewin in the modern era is Jamie Vardy, who embarked on an eight-game scoring spree for Leicester City in 2019.
Why has Calvert-Lewin so hard to stop in recent weeks? A recent opponent's manager explained it aptly.
"He has the perfect timing," the manager said. "He's clever and a excellent striker and he found the timing to arrive just on time."
That instinct and positional sense inside the 18-yard box was what turned him into a beloved player at his previous club.
Pundits highlight the formation change to a 3-5-2 as a key factor, enabling more players to get into the box and occupy defenders, thus provided the striker additional space.
"He is a archetypal centre-forward," commented a former professional. "For the goal... it was a lovely little flick beyond the keeper, a typical centre-forward's goal."
"I've been through a lot since then. Lots of highs and lots of downs. A test of resolve 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 "among the elite strikers" in the competition.
Calvert-Lewin's return to form has inevitably ignited discussions of an England return.
The former Sheffield United player has 11 England appearances, netting four goals, but has not played for the country since the previous European Championship.
Pundits feel the striker will be in contention for the World Cup squad if he can maintain this form.
"He looks as fit as he has in a while," one said. "If he continues this level of form... then he's going to be in a debate for a World Cup place."
But, the battle for places behind Harry Kane is fierce.
Ollie Watkins of Aston Villa, following a decisive two goals versus Chelsea, is right now seen as ahead in the selection race, according to some assessment.
"If you compare the two players, Watkins possesses the edge in terms of using his pace to stretch teams," it was stated.
"He also has the edge when it comes to making a decisive impact at a major tournament."
Ultimately, whether Calvert-Lewin is part of the squad might come down to how many out-and-out strikers the national team coach decides to take.
"I think it might hinge on whether he includes two or three centre-forwards," an pundit summarized. "If it is three, he definitely has a chance."
