A solitary goal in his initial ten top-flight outings this season had numerous questioning whether Dominic Calvert-Lewin's best days were behind him.
But, a mere four weeks later, he has become the hottest attacker in England following 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, seeing him become the highest English scorer in the Premier League this term.
The 28-year-old joined Leeds United on a free transfer in the summer, after a nine-year stint with Everton that was hampered by injuries in its latter stages.
However, the statistics underpinning his revival in Daniel Farke's new fast-breaking 3-5-2 setup are genuinely remarkable.
His six-game scoring run sees him in prestigious company as only the 11th English player to score in six or more straight Premier League fixtures.
To put that into perspective, even England captain Harry Kane did not achieve a run of this length - his longest is two separate five-match streaks.
And the sole English striker to better Calvert-Lewin in recent years is Jamie Vardy, who went on an eight-game scoring streak for Leicester City in 2019.
Why has Calvert-Lewin so tough to stop in the past month? A recent opponent's manager described it succinctly.
"He has the ideal timing," the manager remarked. "He's intelligent and a really good striker and he found the timing to arrive at the perfect moment."
That nose for goal and timing inside the 18-yard box was what turned him into a popular figure at his former team.
Pundits highlight the tactical shift to a 3-5-2 as a significant factor, allowing a greater number of players to occupy the box and occupy defenders, thereby given the striker a little more space.
"He is a archetypal centre-forward," noted a former professional. "For the goal... it was a lovely little flick beyond the keeper, a textbook centre-forward's goal."
"I've experienced a lot since then. Lots of highs and lots of lows. A test of mentality and I've persisted and kept going... I've had faith and here I am now."
His manager has voiced no surprise at this rich vein of form, stating again that the player is "among the elite strikers" in the division.
Calvert-Lewin's resurgence has predictably fueled conversations of an England recall.
The ex- Sheffield United player has 11 England caps, scoring four goals, but has not represented the national team since the most recent European Championship.
Pundits feel the striker will be in the mix for the World Cup squad if he can sustain this standard.
"He looks as in shape as he has in a considerable period," one commented. "If he continues this level of form... then he's going to be in a discussion for a World Cup place."
But, the battle for places as backup to Harry Kane is incredibly tough.
Ollie Watkins of Aston Villa, coming off a decisive double against Chelsea, is presently considered to be in front 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 said.
"He also possesses the edge when it comes to making a meaningful impact at a major tournament."
In the end, whether Calvert-Lewin will be the squad might come down to how many out-and-out strikers the head coach decides to include.
"I think it might hinge on whether he includes two or three centre-forwards," an expert added. "If it is three, he certainly has a chance."
