Dunno with the refresh upgrades tbh. They seem to do it differently every year. I remember one year there was a French striker in the Seria who’s 1st inform got upgraded to the same rating as the sif and the sif stayed the same
It wasn’t the top 50, it was the top 50 with a minimum 3 upgrade in career mode. Can’t see them repeating this as it was stupid and everyone moaned. Literally nobody thought it was a good idea, apart from maybe the devs who had less work to do.
