Only one goal in his initial ten Premier League appearances this campaign had numerous wondering if Dominic Calvert-Lewin's peak were over.
But, a mere four weeks afterwards, he stands as the most discussed forward in England following netting 7 goals in six straight games.
His newest finish, in a 1-1 draw against Sunderland, elevated his tally to eight, making him the top English goalscorer in the Premier League so far this season.
The 28-year-old joined Leeds United on a Bosman move in the summer, after a nine-year spell with Everton that was blighted by fitness issues in its latter stages.
However, the data behind his resurgence in Daniel Farke's new fast-breaking 3-5-2 setup are truly impressive.
His six-game scoring streak sees him in exclusive company as only the 11th English player to score in six or more consecutive Premier League matches.
To provide context, even England captain Harry Kane never managed a run of this length - his best stands at two separate five-match runs.
And the sole English striker to better Calvert-Lewin in recent memory is Jamie Vardy, who embarked on an eight-game scoring streak for Leicester City in 2019.
What has made Calvert-Lewin so hard to stop in this period? A previous opponent's manager explained it aptly.
"He has the perfect timing," the manager stated. "He's clever 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 established him as a fan favourite at his former team.
Experts point to the formation change to a 3-5-2 as a key factor, enabling a greater number of players to occupy the box and occupy defenders, thus created the striker some extra space.
"He is a archetypal centre-forward," noted a former professional. "For the goal... it was a neat little finish beyond the keeper, a textbook centre-forward's goal."
"I've endured a lot since then. Lots of ups and lots of downs. A test of resolve and I've persevered and kept going... I've backed myself and here I am now."
His manager has voiced complete confidence at this hot streak, reiterating that the player is "one of the best strikers" in the league.
Calvert-Lewin's resurgence has predictably fueled discussions of an England recall.
The ex- Sheffield United player has eleven England appearances, scoring four goals, but has not featured for the Three Lions since the most recent European Championship.
Pundits think the striker will be in consideration for the World Cup squad if he can sustain this standard.
"He looks as in shape as he has in a while," one commented. "If he continues this level of form... then he's going to be in a conversation for a World Cup place."
However, the battle for places behind Harry Kane is intense.
Ollie Watkins of Aston Villa, following a decisive double against Chelsea, is currently considered to be in front in the pecking order, according to some opinion.
"If you compare the two players, Watkins possesses the edge in terms of using his pace 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 is part of the squad may depend on how many out-and-out strikers the England manager decides to select.
"I think it might hinge on whether the manager takes two or three centre-forwards," an analyst added. "If it is three, he certainly has a chance."
