REPLICA (Fan Version) VS AUTHENTIC (Player Version) SIZES: 

Player Version jersey was designed for the soccer player, and the jersey fit was close fit. 

So when you choose a player version size, you should choose 1 or 2 sizes up of the fan version jersey you wear.

Now that you can tell the difference between a player version and a fan version jersey, you need only to decide which fit and feel you’re looking for.
