Current club 

Oh come on!!  A little common sense and being less nit picky?!  Obviously he doesn't play for "free agent FC" or "FC Unattached"!  Or instead of using "free agent" or "unattached", I actually put for his current club, "currently without a club"...  You're going to interpret that as De Jong being contracted to "FC currently without a club"?!?  You're also telling me that when a player is listed in a national team article and they're club is listed as "unattached", because they're literally without a club, they actually play for a team called "Unattached FC" or the like?! LOL!!!  Come on!!
