Just one goal in his first ten top-flight games this season had many questioning whether Dominic Calvert-Lewin's prime were behind him.
Yet, a just four weeks on, he has become the hottest attacker in England after bagging seven goals in six consecutive games.
His latest finish, in a tie against Sunderland, brought his total to eight, seeing him become the highest English scorer in the Premier League so far this season.
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 fitness issues in its closing stages.
But, the data underpinning his comeback in Daniel Farke's new fast-breaking 3-5-2 system are truly impressive.
His six-match scoring sequence puts him in elite company as only the 11th English player to score in six or more consecutive Premier League matches.
To provide context, even England captain Harry Kane never managed a run this long - his best remains two individual five-match runs.
And the only English striker to surpass Calvert-Lewin in recent years is Jamie Vardy, who embarked on an eight-game scoring streak for Leicester City in 2019.
What is behind Calvert-Lewin so tough to stop in recent weeks? A latest opponent's manager explained it succinctly.
"He has the perfect timing," the manager said. "He's clever and a excellent striker and he found the timing to arrive just on time."
That nose for goal and timing inside the 18-yard box was what turned him into a beloved player at his former team.
Experts note the tactical shift to a 3-5-2 as a key factor, allowing a greater number of players to occupy the box and occupy defenders, thereby provided the striker some extra space.
"He is a traditional centre-forward," commented a former professional. "For the goal... it was a neat little finish beyond the keeper, a classic centre-forward's goal."
"I've been through a lot since then. Lots of ups and lots of downs. A challenge of mentality and I've persevered and kept going... I've believed in myself and now I'm reaping the rewards."
His manager has shown no surprise at this hot streak, stating again that the player is "a top strikers" in the league.
Calvert-Lewin's resurgence has inevitably sparked conversations of an England return.
The former Sheffield United player has eleven England caps, scoring four goals, but has not played for the Three Lions since the most recent European Championship.
Analysts feel the striker will be in the mix for the World Cup squad if he can sustain this standard.
"He looks as sharp as he has in a considerable period," one remarked. "If he continues this level of form... then he's going to be in a debate 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 hierarchy, according to some analysis.
"If you look at the two players, Watkins holds the advantage in terms of using his pace to test teams," it was said.
"He also holds the advantage when it comes to making a meaningful impact at a major finals."
Finally, whether Calvert-Lewin makes it to the squad could hinge on how many natural strikers the head coach decides to take.
"I think it might hinge on whether he includes two or three centre-forwards," an expert added. "If it is three, he certainly has a chance."
