Just one goal in his initial ten English top division appearances this campaign had many wondering whether Dominic Calvert-Lewin's best days were behind him.
Yet, a only four weeks later, he has become the most discussed striker in England after netting seven goals in 6 straight games.
His newest finish, in a 1-1 draw against Sunderland, brought his season's haul to eight, seeing him become the leading English goalscorer 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 marred by injuries in its closing stages.
Yet, the statistics underpinning his resurgence in Daniel Farke's new fast-breaking 3-5-2 formation are truly remarkable.
His six-game scoring sequence sees him in prestigious company as just the 11th English player to score in six or more successive Premier League fixtures.
To provide context, even England captain Harry Kane never managed a run lasting this many games - his longest is two individual five-match streaks.
And the only English striker to better Calvert-Lewin in recent memory is Jamie Vardy, who went on an eight-game scoring spree for Leicester City in 2019.
What is behind Calvert-Lewin so hard to stop in recent weeks? A recent opponent's manager described it perfectly.
"He has the impeccable timing," the manager said. "He's intelligent and a genuinely top-class striker and he found the timing to arrive exactly when needed."
That nose for goal and timing inside the penalty area was what made him a popular figure at his previous club.
Analysts note the tactical shift to a 3-5-2 as a major factor, enabling more players to get into the box and occupy defenders, thus given the striker additional space.
"He is a traditional centre-forward," noted a former professional. "For the goal... it was a exquisite little finish beyond the keeper, a typical centre-forward's goal."
"I've endured a lot since then. Lots of highs and lots of downs. A challenge of resolve and I've persevered and kept going... I've believed in myself and now I'm reaping the rewards."
His manager has shown little astonishment at this hot streak, emphasizing that the player is "one of the best strikers" in the competition.
Calvert-Lewin's scoring run has predictably fueled discussions of an England return.
The ex- Sheffield United player has eleven England appearances, scoring four goals, but has not played for the Three Lions since the most recent European Championship.
Observers think the striker will be in the mix for the World Cup squad if he can keep up this level.
"He looks as fit as he has in a considerable period," one remarked. "If he sustains this level of form... then he's going to be in a discussion for a World Cup place."
But, the battle for places supporting Harry Kane is incredibly tough.
Ollie Watkins of Aston Villa, following a decisive two goals against Chelsea, is presently seen as ahead in the selection race, according to some analysis.
"If you contrast the two players, Watkins possesses the edge in terms of using his pace to test teams," it was stated.
"He also has the advantage when it comes to making a meaningful impact at a major finals."
In the end, whether Calvert-Lewin will be the squad may depend on how many out-and-out strikers the head coach decides to select.
"I think it might come down to whether he selects two or three centre-forwards," an pundit summarized. "If it is three, he absolutely has a chance."
