fifa 16 winter upgrades is going on now, ea has released 2 complete lists of fifa 16 ultimate team winter upgrades. and the rest two batches will be released on 19th february and 26th february(every friday throughout the month of february). 

many players are looking forward to each friday, and hoping to get a good pay back from the winter upgrades investment(in especial the investment on if players). here are some rules and faq which was published by ea about fut 16 winter upgrades you should know: 

upgrades apply to new non-inform players found in packs. non-if players in your club will not receive an upgrade.

if an upgraded player’s new ovr rating equals or surpasses his existing first in-form’s rating, his ifs will get an upgrade.

if an upgraded player’s new ovr rating does not equal or surpass his existing in-form’s rating, his ifs will not get an upgrade. (ex: jamie vardy went from 71 to 75 ovr, his 82 record breaker will not receive an upgrade)

however, if an upgraded player with an existing if gets upgraded across quality tiers (eg. silver to gold), his lower-quality if will not get an upgrade. this preserves the in-form’s high value. (ex: jack butland’s item is now gold, but his silver in-form will not receive an upgrade and stays silver.)

if you already own the in-form version of an upgraded player in your club, your if will get an upgrade.
