There are MANY other elements that determine if one is signed by a club in a 'top league'..
When yuh look pon a player you should be able to determine based on his abilities and play at the International level if he is 'World Class' or not..
Are his football skills (decision making,control, passing, vision, dribbling) at a World Class level ?
Could he play for a Team in the FIFA Top 10 or would he look out of place... be a liability ?
How does he look playing against the Top Teams..
