A solitary goal in his initial ten English top division appearances this campaign had numerous doubting whether Dominic Calvert-Lewin's prime were in the past.
Yet, a mere four weeks on, he has become the hottest striker in England following netting seven goals in 6 consecutive games.
His most recent strike, in a tie against Sunderland, brought his tally to eight, making him the highest English scorer in the Premier League this campaign.
The 28-year-old joined Leeds United on a free transfer in the summer, following a nine-year spell with Everton that was marred by injuries in its final stages.
But, the numbers supporting his revival in Daniel Farke's new fast-breaking 3-5-2 formation are genuinely remarkable.
His six-match scoring run puts him in exclusive company as just the 11th English player to score in six or more consecutive Premier League matches.
To frame that statistic, even England captain Harry Kane never managed a run of this length - his top remains two distinct five-match streaks.
And the only English striker to surpass Calvert-Lewin in the modern era is Jamie Vardy, who produced an eight-game scoring run for Leicester City in 2019.
Why has Calvert-Lewin so tough to stop in recent weeks? A recent opponent's manager described it succinctly.
"He has the perfect timing," the manager said. "He's intelligent and a really good striker and he found the timing to arrive just on time."
That instinct and timing inside the box was what made him a popular figure at his former team.
Pundits note the tactical shift to a 3-5-2 as a key factor, enabling more players to occupy the box and occupy defenders, thereby provided the striker a little more space.
"He is a archetypal centre-forward," observed a former professional. "For the goal... it was a exquisite little touch beyond the keeper, a classic centre-forward's goal."
"I've been through 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 here I am now."
His manager has expressed little astonishment at this purple patch, stating again that the player is "one of the best strikers" in the division.
Calvert-Lewin's return to form has inevitably fueled talks of an England call-up.
The former Sheffield United player has eleven England appearances, scoring four goals, but has not played for the country since the most recent European Championship.
Pundits believe the striker will be in the mix for the World Cup squad if he can maintain this level.
"He looks as sharp as he has in a long time," one said. "If he continues this level of form... then he's going to be in a conversation for a World Cup place."
But, competition for places as backup to Harry Kane is fierce.
Ollie Watkins of Aston Villa, following a match-winning double versus Chelsea, is right now regarded as in front in the selection race, according to some opinion.
"If you look at the two players, Watkins has 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 decisive impact at a major tournament."
Ultimately, whether Calvert-Lewin will be the squad might come down to how many natural strikers the national team coach decides to take.
"I think it might depend on whether the manager takes two or three centre-forwards," an pundit added. "If it is three, he absolutely has a chance."
