A solitary goal in his initial ten top-flight games this season had plenty of questioning whether Dominic Calvert-Lewin's best days were behind him.
However, a only four weeks later, he has become the hottest attacker in England following scoring 7 goals in 6 consecutive games.
His latest goal, in a 1-1 draw against Sunderland, took his season's haul to eight, establishing him as the leading English scorer in the Premier League so far this season.
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 setbacks in its latter stages.
Yet, the statistics supporting his resurgence in Daniel Farke's new fast-breaking 3-5-2 formation are truly remarkable.
His six-match scoring sequence puts him in elite company as only the 11th English player to score in six or more straight Premier League outings.
To frame that statistic, even England captain Harry Kane was unable to produce a run lasting this many games - his longest is two separate five-match streaks.
And the sole English striker to outdo Calvert-Lewin in recent years is Jamie Vardy, who went on an eight-game scoring spree for Leicester City in 2019.
What is behind Calvert-Lewin so difficult to stop in this period? A recent opponent's manager summed it up succinctly.
"He has the perfect timing," the manager remarked. "He's clever and a excellent striker and he found the timing to arrive at the perfect moment."
That nose for goal and positional sense inside the box was what made him a fan favourite at his previous club.
Pundits highlight the system adjustment to a 3-5-2 as a key factor, allowing a greater number of players to enter the box and occupy defenders, thus provided the striker a little more space.
"He is a classic centre-forward," observed a former professional. "For the goal... it was a lovely little flick 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 character and I've persevered and kept going... I've backed myself and this is the result."
His manager has voiced complete confidence at this rich vein of form, reiterating that the player is "among the elite strikers" in the competition.
Calvert-Lewin's return to form has naturally ignited talks of an England recall.
The former Sheffield United player has 11 England caps, netting four goals, but has not played for the country since the last European Championship.
Pundits feel the striker will be in consideration for the World Cup squad if he can maintain this standard.
"He looks as fit as he has in a considerable period," one said. "If he sustains this level of form... then he's going to be in a conversation for a World Cup place."
Yet, competition for places behind Harry Kane is incredibly tough.
Ollie Watkins of Aston Villa, coming off a match-winning two goals versus Chelsea, is presently seen as in front in the selection race, according to some analysis.
"If you look at the two players, Watkins possesses the edge in terms of using his speed to get behind teams," it was stated.
"He also has the advantage when it comes to making a significant impact at a major tournament."
Ultimately, whether Calvert-Lewin will be the squad might come down to how many out-and-out strikers the England manager decides to take.
"I think it might hinge on whether the manager selects two or three centre-forwards," an analyst summarized. "If it is three, he absolutely has a chance."
