A solitary goal in his first ten Premier League outings this campaign had plenty of questioning whether Dominic Calvert-Lewin's prime were over.
Yet, a mere four weeks afterwards, he stands as the hottest forward in England after netting 7 goals in 6 consecutive games.
His most recent goal, in a tie against Sunderland, elevated his total to eight, establishing him as the leading English scorer in the Premier League this campaign.
The 28-year-old joined Leeds United on a free transfer in the summer, following a nine-year stint with Everton that was marred by fitness issues in its latter stages.
However, the data behind his comeback in Daniel Farke's new counter-attacking 3-5-2 formation are truly impressive.
His six-match scoring streak sees him in elite company as only the 11th English player to score in six or more straight Premier League matches.
To put that into perspective, even England captain Harry Kane did not achieve a run this long - his best is two distinct five-match streaks.
And the only English striker to outdo Calvert-Lewin in recent years is Jamie Vardy, who produced 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 at the perfect moment."
That instinct and positional sense inside the 18-yard box was what made him a fan favourite at his former team.
Experts note the formation change to a 3-5-2 as a major factor, helping more players to get into the box and occupy defenders, which has provided the striker some extra space.
"He is a classic centre-forward," commented a former professional. "For the goal... it was a lovely little touch beyond the keeper, a typical centre-forward's goal."
"I've been through a lot since then. Lots of ups and lots of lows. A test of character and I've persevered and kept going... I've had faith and here I am now."
His manager has shown little astonishment at this hot streak, emphasizing that the player is "among the elite strikers" in the division.
Calvert-Lewin's scoring run has predictably fueled discussions of an England return.
The former Sheffield United player has 11 England caps, scoring four goals, but has not represented the national team since the most recent European Championship.
Observers believe the striker will be in the mix for the World Cup squad if he can keep up this standard.
"He looks as fit as he has in a while," one remarked. "If he continues this level of form... then he's going to be in a discussion for a World Cup place."
However, competition for places behind Harry Kane is intense.
Ollie Watkins of Aston Villa, following a match-winning double versus Chelsea, is presently regarded as in front in the pecking order, according to some opinion.
"If you contrast the two players, Watkins holds the advantage in terms of using his pace to stretch teams," it was stated.
"He also has the advantage when it comes to making a meaningful impact at a major tournament."
Finally, whether Calvert-Lewin makes it to the squad may depend on how many natural strikers the England manager decides to include.
"I think it might come down to whether he includes two or three centre-forwards," an analyst summarized. "If it is three, he certainly has a chance."
