Not sure if there's a topic on this yet but anyway, I noticed last week that granqvist the CB from Krasnodar sky rocketed from around 800 coins when his NIF was in packs to a peak of about 8k when his IF was in packs. This was because he is essentially needed for the krasnodar sbc or at least most people assume he is due to laziness or futbin having him in most of their completed challenges. So when not in packs his demand massively rises while supply is not there.
Does anyone already invest in this way? Any tips on players etc would be appreciated.
