Investment: Theo Hernandez
TOTY defenders come out on Tuesday. Last year their golds saw a substantial increase in price while OOP (see Dias and Cancelo). Theo Hernandez just went out of packs a month ago and rose from 25k to 35k, so I think there is a good chance he could increase again.
Theo Hernandez: PSX 23k PC 27k (~ 5k profit target)
It is likely his card will be out of packs for a week and a half until Friday, February 3rd. I think he will gradually increase over that time, but as always, sell when you are happy with the profit.
