Taiwo Atieno II   Just noticed your question on my talkpage  somehow Id missed it  My understanding of the WP convention is that if a player is rostered with a club for any significant period of time that club is listed in his infobox even if the player makes no appearances for the club  If a player only passes through briefly and makes no appearances for the club however it isnt listed  As for the other question Id say its fairly common in the US for a player to spend a very brief period on the roster of one club before being traded to another for instance in the  expansion draft expansion franchise Toronto FC snapped up a couple of guys simply for their trade value and then proceeded to deal them to other teams in exchange for players they actually wanted  I believe that in circumstances like this we wouldnt list a Toronto FC tenure in a players infobox  Overall my understanding of the guidelines here is pretty shakey to be honest
