Predicting anything is a notoriously tricky business - mainly because nobody can actually predict the future.
Until that soothsayer is found/discovered/created/born we'll have to make do with moderately informed 'experts'.
We all agree on who the current best players in the world are - Leo Messi, Cristiano Ronaldo, etc. But what about in seven years time?
Who will be the Messi's and Ronaldo's of the year 2020? Well, we've looked at data taken from the video game FIFA 14, which ranks the best young players in the world by their 'potential'.
So who has the most potential under the age of 23 on the game - and by virtue, which player do EA Sports expect to be the best in the world one day?
Well you'll just have to scroll through the countdown to find out.
Here's the top 20, feel free to have your say below if you agree or disagree with the selections...
