Pro Players

Pro Players items are unique improved cards assigned by EA Sports to professional football players in a bid to make friends and gain exposure. The real players who have an existing relationship and play FUT are more likely to receive an item from themselves.

Pro Players are untradeable items, and you cannot get one unless you are a professional footballer. Therefore, they are unavailable in packs, squad building challenges, or objectives. If you play against someone with one of these cards, you are playing against a professional football player.
