Only one goal in his first ten English top division games this season had many doubting whether Dominic Calvert-Lewin's prime were behind him.
Yet, a only four weeks on, he stands as the hottest attacker in England after netting seven goals in six consecutive games.
His newest finish, in a stalemate against Sunderland, elevated his tally to eight, establishing him as the highest English goalscorer in the Premier League this campaign.
The 28-year-old moved to Leeds United on a Bosman move in the summer, following a nine-year stint with Everton that was blighted by setbacks in its final stages.
Yet, the statistics underpinning his resurgence in Daniel Farke's new counter-attacking 3-5-2 system are truly remarkable.
His six-match scoring run places him in exclusive company as just the 11th English player to score in six or more straight Premier League fixtures.
To frame that statistic, even England captain Harry Kane never managed a run this long - his longest remains two separate 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 streak for Leicester City in 2019.
Why has Calvert-Lewin so difficult to stop in this period? A previous opponent's manager described it succinctly.
"He has the impeccable timing," the manager remarked. "He's smart and a really good striker and he found the timing to arrive exactly when needed."
That natural ability and positional sense inside the penalty area was what turned him into a fan favourite at his previous club.
Analysts note the formation change to a 3-5-2 as a major factor, enabling a greater number of players to occupy the box and occupy defenders, which has given the striker additional space.
"He is a traditional centre-forward," observed a former professional. "For the goal... it was a lovely little finish beyond the keeper, a typical centre-forward's goal."
"I've endured a lot since then. Lots of ups and lots of lows. A test of resolve and I've persevered and kept going... I've backed myself and this is the result."
His manager has shown little astonishment at this rich vein of form, stating again that the player is "one of the best strikers" in the competition.
Calvert-Lewin's resurgence has naturally fueled discussions of an England call-up.
The former Sheffield United player has 11 England caps, scoring four goals, but has not played for the Three Lions since the most recent European Championship.
Analysts think the striker will be in the mix for the World Cup squad if he can keep up this form.
"He looks as fit as he has in a long time," one remarked. "If he maintains this level of form... then he's going to be in a debate for a World Cup place."
However, the battle for places as backup to Harry Kane is fierce.
Ollie Watkins of Aston Villa, coming off a match-winning two goals versus Chelsea, is right now considered to be ahead in the hierarchy, according to some analysis.
"If you compare the two players, Watkins has the edge in terms of using his pace to test teams," it was stated.
"He also has 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 might come down to how many out-and-out strikers the head coach decides to include.
"I think it might depend on whether he includes two or three centre-forwards," an pundit summarized. "If it is three, he definitely has a chance."
