No the issue is that there's many people like yourself who get led on to believe that data is the absolute pivotal aspect when it comes to recruitment at the clubs you mention, when data is in reality being used to gain incremental gains. But the biggest gains come from the actual eye test when it comes identifying players for a set way of playing the game and that's where the biggest gains come from. But we as a club are failing in that aspect and jumping straight to achieving marginal gains cannot be achieved via data if you fail to understand how you want to play and who you want to sign to carry out the tactical blueprint via the eye test and your own brain. This is where the biggest gains are and if you achieve this then the marginal gains make the recruitment process even more effective. Those clubs you mention in your post have achieved close to maximinum gains via their scouting department, especially Liverpool and their data analytics has solidified that by providing incremental gains on top of the work done by Barry Hunter and Dave Fallows who are known to be best in class ever since they were poached from Man City in 2012. Liverpool's recruitment is being led by both these men.The reason you can't define a recruitment system that's data led is because you'd either end up describing what happens at clubs like Liverpool/Bournemouth or none at all.
Now as this is the Geovany Quenda thread I think it's important to get the discussion back on track. And I think it's also now probably better to discuss your out of possession statistics when it comes to 17 year old Quenda who is primarily a attacker.
What this further proves to me is that you're using statistics wrong for a young wide/advanced attacking player whose primary role will be in-possession and not out of possession. The statistics you brought up are best applied to the central midfield and the CBs who form the central core of the team and occupy positions in either the most vulnerable area defensively or the most penetrative as far as breaking lines in-possession, especially against the oppositions high press.
And the stats you put forward for Quenda quite clearly show me that you're using the statistics wrong. You're either ignoring or are oblivious to the tactical concepts of playing a more expansive game hence you're throwing out random stats to support a claim on a player who shouldn't be judged on what he will bring about out of possession at 17 years old but rather what he will provide in-possession as a attacker in a system of play that is geared up to play more proactive as a team and hence impose themselves on the opposition.
It's why Ralf Rangnick said that you have to first understand how you want play or else it's like trying find a needle in a haystack when it comes to recruitment.
