Only one goal in his initial ten English top division appearances this campaign had many wondering whether Dominic Calvert-Lewin's peak were in the past.
However, a just four weeks on, he is the most talked-about forward in England following scoring seven goals in six consecutive games.
His most recent strike, in a tie against Sunderland, elevated his total to eight, establishing him as the highest English scorer in the Premier League this term.
The 28-year-old moved to Leeds United on a free transfer in the summer, after a nine-year stint with Everton that was marred by injuries in its latter stages.
Yet, the statistics supporting his comeback in Daniel Farke's new counter-attacking 3-5-2 formation are extremely impressive.
His six-match scoring streak sees him in elite company as just the 11th English player to score in six or more consecutive Premier League fixtures.
To frame that statistic, even England captain Harry Kane never managed a run lasting this many games - his longest is two separate five-match runs.
And the sole English striker to outdo Calvert-Lewin in recent years is Jamie Vardy, who produced an eight-game scoring run for Leicester City in 2019.
What is behind Calvert-Lewin so tough to stop in the past month? A latest opponent's manager summed it up perfectly.
"He has the impeccable 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 popular figure at his previous club.
Analysts note the system adjustment to a 3-5-2 as a key factor, allowing more players to get into the box and occupy defenders, thus provided the striker additional space.
"He is a classic centre-forward," observed a former professional. "For the goal... it was a exquisite little finish beyond the keeper, a classic centre-forward's goal."
"I've endured a lot since then. Lots of highs and lots of lows. A test of resolve and I've persisted and kept going... I've backed myself and here I am now."
His manager has shown little astonishment at this purple patch, stating again that the player is "a top strikers" in the competition.
Calvert-Lewin's return to form has naturally sparked discussions of an England recall.
The former Sheffield United player has eleven England caps, netting four goals, but has not played for the country since the last European Championship.
Observers feel 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 considerable period," one commented. "If he sustains this level of form... then he's going to be in a conversation for a World Cup place."
However, competition for places supporting Harry Kane is incredibly tough.
Ollie Watkins of Aston Villa, fresh off a decisive two goals against Chelsea, is presently regarded as leading in the selection race, according to some analysis.
"If you compare the two players, Watkins holds the advantage in terms of using his pace to get behind teams," it was noted.
"He also has the advantage when it comes to making a decisive impact at a major finals."
Finally, whether Calvert-Lewin will be the squad may depend on how many specialist strikers the head coach decides to take.
"I think it might come down to whether he selects two or three centre-forwards," an expert summarized. "If it is three, he certainly has a chance."
