What do Champions League cards do?
Only the 'live' items have the potential to receive upgrades in Ultimate Team, these are the UCL Road to the Final cards.
The highest performing players in the Champions League receive Team of the Tournament cards, these cards' stats are boosted from their base card but are not live items.
UCL Rares and Non-Rares are simply players whose teams are in the Champions League and do not receive any stat boosts from their base card.
UCL Live Road to the Final Upgrades
All Champions League RTTF items start with an upgrade at the launch of the event.
From there, the player’s Road To The Final item receives a further upgrade each time their team succeeds at select stages throughout the tournament.
Road To The Final players do not need to be selected or have played in each stage to receive an upgrade.
If a player is no longer on the roster of a club in either tournament, they will not receive any further upgrades.
Likewise, if a player’s team gets knocked out of either tournament, they will no longer receive any upgrades.
Once a certain round of the competition is over, Road To The Final items could take up to a few days to update in-game.
