A solitary goal in his initial ten Premier League appearances this campaign had many doubting if Dominic Calvert-Lewin's best days were in the past.
However, a only four weeks afterwards, he stands as the most talked-about forward in England following bagging 7 goals in 6 straight games.
His most recent strike, in a stalemate versus Sunderland, elevated his season's haul to eight, establishing him as the leading English goalscorer in the Premier League this campaign.
The 28-year-old moved to Leeds United on a free transfer in the summer, after a nine-year stint with Everton that was hampered by fitness issues in its latter stages.
But, the data supporting his resurgence in Daniel Farke's new fast-breaking 3-5-2 system are truly notable.
His six-game scoring sequence sees him in exclusive company as only the 11th English player to score in six or more straight Premier League outings.
To put that into perspective, even England captain Harry Kane did not achieve a run this long - his best remains two individual five-match runs.
And the sole English striker to better Calvert-Lewin in the modern era is Jamie Vardy, who produced an eight-game scoring streak for Leicester City in 2019.
Why has Calvert-Lewin so tough to stop in this period? A latest opponent's manager summed it up succinctly.
"He has the perfect timing," the manager stated. "He's intelligent and a excellent striker and he found the timing to arrive at the perfect moment."
That natural ability and positional sense inside the penalty area was what established him as a popular figure at his previous club.
Experts highlight the tactical shift to a 3-5-2 as a significant factor, enabling a greater number of players to occupy the box and occupy defenders, which has provided the striker additional space.
"He is a traditional centre-forward," noted a former professional. "For the goal... it was a lovely little flick beyond the keeper, a classic centre-forward's goal."
"I've experienced a lot since then. Lots of ups and lots of downs. A challenge of resolve and I've persevered and kept going... I've backed myself and here I am now."
His manager has expressed little astonishment at this hot streak, reiterating that the player is "among the elite strikers" in the competition.
Calvert-Lewin's return to form has predictably sparked talks of an England return.
The former Sheffield United player has 11 England caps, netting four goals, but has not featured for the Three Lions since the previous European Championship.
Analysts believe the striker will be in consideration for the World Cup squad if he can keep up 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, competition for places behind Harry Kane is incredibly tough.
Ollie Watkins of Aston Villa, following a match-winning double against Chelsea, is currently seen as ahead in the selection race, according to some analysis.
"If you contrast the two players, Watkins possesses the advantage in terms of using his speed to get behind teams," it was stated.
"He also holds the edge when it comes to making a significant impact at a major tournament."
In the end, whether Calvert-Lewin makes it to the squad may depend on how many specialist strikers the head coach decides to include.
"I think it might depend on whether the manager includes two or three centre-forwards," an expert summarized. "If it is three, he certainly has a chance."
