What's the difference between player version jersey and fan version jersey?

The top quality of the player/fan version, the clothes look the same, but there are many differences in the details.

They have different fabric/manufacturing process/version/structure/price; player/fan version of the product link (because the new season's player version & fan version are different,the common is the difference in size, We recommend that if you buy a player version, you can choose one or two sizes larger than the usual clothes.)
