Eberechi Eze has seemingly been put on this planet to heap misery onto Tottenham Hotspur.
The flashy winger hasn't exactly done much since leaving Crystal Palace and signing for Arsenal in a £67m deal, but he's bagged five times against Spurs after they almost secured his signature last month.
Tottenham were left chagrined after his move was scuppered by Arsenal's interest, but fan worries were (temporarily allayed upon the £52m signing of Xavi Simons from RB Leipzig.
However, Simons was overshadowed by his Gunner counterpart on Sunday evening.
Xavi Simons' performance vs Arsenal
Tottenham are in a Premier League relegation battle. All it takes is a couple of wins to change that narrative, but that is clearly Tudor's focus for the remainder of the campaign, and not catering to far-fetched hopes of winning the Champions League.
To change the narrative, the hard-nosed Croatian will need to bring out the best in Simons, who has at times showed such promise this season but then crumbles when the going gets tough, as was shown during the defeat to Arsenal.
To not score or assist? That's excusable. But to win only one of 16 contested duels is a greivous affront against the paying Spurs supporters, speaking of a lack of commitment or, at the very least, impetus on a day of rivalry. The supporters showed up, sang and roared and bellowed, but Tudor's side wilted away early on and never recovered. Simons was a part of that feeble pack.
It is be unfair to be too scathing about Simons' performance. He has been one of the brighter sparks in recent weeks, and it's unlikely that Eze would have enjoyed the same snappy success had the roles been reversed.
Nonetheless, with James Maddison and Dejan Kulusevski still sidelined, he's struggled to make his mark all season, and it's not just the two senior stars in front of him that he needs to be watching out for.
Spurs already have a future Simons upgrade
In Luca Williams-Barnett, Tottenham have found the latest in a long line of elite prospects who is considered not only good enough to shine for Tottenham but to stand out as one of Europe's best players.
The 17-year-old has been described by U23 scout Antonio Mango as the "most underrated talent in English Academies", but having scored six goals and supplied five assists from ten matches in the Premier League 2 this season, he's beginning to earn the respect he deserves.
Williams-Barnett has already made his professional debut for the Lilywhites, playing a few minutes on the left wing as Thomas Frank's side defeated Doncaster Rovers 3-0. Happier times.
And with six bench appearances from Tottenham's previous eight Premier League outings, it's clear that he's inching closer to a big role in this sinking Spurs ship.
With that in mind, could he be the player to take the number seven shirt from Simons? Williams-Barnett is silky and stylish on the ball, well-developed as an athlete even at this young age.
Back at the start of the season, content creator Ronaldo Brown said that Simons has been "swallowed in the Premier League", his lack of physicality and composure letting him down.
There's every chance that Williams-Barnett would encounter similar hurdles right now, but given the success he is already enjoying and the faith entrusted in him by Tottenham's senior coaching staff across the campaign, there's every reason for Tudor to start handing him some opportunities. He might just surprise a few.
Could he end up being not just Tottenham's homemade Simons upgrade but their own version of Eze too? He's flashy and boasts a range of attacking qualities; it might just be the case.
He's since steadied himself, but is it enough for him to be a superstar for a team like Tottenham? In Williams-Barnett, the Dutchman might just find the decision made for him, should he not turn things around soon.
