I assume you don't dispute that the Bundesliga is weaker than the Premier League though?
So my point is, how do you translate and compare statistics from one league to another,
As I said, Data and statistics is something I am very interested in, but after a decade studying them in the context of horse racing, I am firmly of the opinion statistics and Data can be incredibly dangerous in the wrong hands.
I spent years trying to create a "perfect" model for rating a horses performance so I could rate and compare the performance of a horse over 7F on soft ground at Newmarket against the performance of a horse over 6F on firm ground at Chester but it doesnt ever work. If you take the numbers literally and don't use your eye and experience, you will lose.
So going back to the point of this thread...occasionally in horse racing I will see a horse suddenly post an exceptional performance or "number" that is an outlier from the average. Very occasionally, this horse genuinely has improved, but 90% of the time the horse benefitted from some kind of unseen advantage or set of circumstances that resulted in a well above average performance that can never be replicated.
My concern with Nkunku is as follows....at face-value, his career statistics have not been standout before this season. He's had just the two caps for France. He is 24 and (no disrespect to Leipzig) hasnt been snapped up by a "big" club.
So, going back to racing, if I see a horse who has ran 25 times between CL4 and CL5 races suddenly post a performance that would rate as a CL2 performance, seemingly out of nowhere, I dismiss it. Because for every 1 time I am wrong to dismiss it, I am right 9 times. So i dont need to watch the performance or consider backing the horse. I intrinsically know the vast majority of 5yo horses don't suddenly improve 20lbs in one run. Likewise, I don't need to watch hours of video footage to say generally that 24yo strikers/CAMs with one standout season under their belt and who turn 25 in 5-months dont, as a general rule, become elite players.
So, there are people on this forum who are far more knowledgeable than me when it comes to using Data and statistics to assess a footballer...but purely at face vale, I would question is a lad who will be 25 early in next season really an elite talent or going to become an elite talent?
Genuine question for
@BenitoSTARR - how did Depay's stats look? Or DvdB? Or Pepe? Or Jadon Sancho? Or Timo Werner?
Did they standout? Would you have recommended signing these players based on their statistics?
