A few have questioned whether it's fair to include new Premier League arrivals in the rankings, particularly when they score extremely highly, á la Victor Wanyama, Jesus Navas and Stevan Jovetic.
The list wouldn't be nearly as much fun without those inclusions, but the pretense that it's difficult to accurately grade a new player coming into the EPL is extremely valid.
However, it's the same process every professional scout, coach and manager goes through when mulling over a new signing, and it's part knowledge, part identification of talent and part luck in every single instance.
"How do you know Wanyama is better than Youssouf Mulumbu before he's kicked a Premier League ball?" is a legitimate question, and you have to factor in what you've seen from the new player in other leagues.
Wanyama has excelled on the UEFA Champions League platform, scored against Barcelona and dominated Juventus for 20- to 30-minute spells with Celtic. His size, physique and natural instincts (the way he moves and reacts to what's happening around him) all point toward a successful Premier League career.
There is no exact science to it, but it's not just a gut feeling or a guess either, and that's represented throughout every level of football. After all, Sir Alex Ferguson spent £7 million Bebe.
