We have created this FAQ to make it easier to understand how Squad Battles works.
FIFA 21 Squad Battles is a single player game mode where you take on other squads from the FUT community, to earn rewards and move up the leaderboards.

FIFA 21 Squad Battles
FUT Champs has much better rewards but Squad Battles is also a good option for who doesn’t like to play against real opponents or doesn’t have a good connection.
You don’t need it. Everyone is invited. You just need to enter and play. As simple as that.
Sure. That’s our job.
Squad Battles has three windows:

This is where you set the difficulty level and pick the opponent you will play. You can see his squad, formation, tactics, kits, stadium and where he is from. If you already played against him, you will see a light blue tick. In each round, there are four new teams to play against. You can also play unlimited times against the featured squad and the TOTW, which are refreshed weekly.

Also known as Leaderboards, this is where you can see how well you are going and which rewards you can get. Just like in FUT Champions, you have several tiers, that goes from Bronze 3 to Elite 1 and also TOP 200. Remember that the event only ends on Sunday night, so your current ranking is not the final one.

TOP 200
This is where you can see who are the best Squad Battles players at that moment.
Yes, it may happen if you have played at least one match on Squad Battles, Draft (online and single player), FUT Champions or Division Rivals.
Battle Points are earned at the end of each Squad Battles match. They are used to determine your Rank in the weekly Squad Battles competition.

You can see the Battle Points formula clicking here.
In Squad Battles, the Battle Points you earn during the week determines your Rank in the weekly competition. Each Rank can only hold a certain percentage of the players competing in Squad Battles during the current weekly competition. Ranks are determined by the average score among all competitors. To get the highest rank, you will need to earn more Battle Points than all other players in the weekly competition. The percentage breakdown of each Rank can be seen in-game.

If you are one of the Top 200 players in a weekly Squad Battles competition, you’ll earn rewards based on your position in the Top 200.
Yes, you can. If you start off playing Squad Battles matches early in the week and earn a lot of Battle Points, you might initially be in a top Rank. But if you don’t continue playing matches throughout the rest of the week or earn less Battle Points, other players could still be playing and earning Battle Points. That means your Rank could drop, if they out-earn you and move up.

On the flip side, you could also move up a Rank if players don’t out-earn you.
If two or more players have the same points, the player with fewer games played gets the higher position.
The leaderboard updates roughly every five minutes.
Yes. Squad Battles can also be used as an alternative placement method to help you find your level in Division Rivals. The first 30 matches played in Squad Battles will factor the difficulty you play at, and the results of your games, into your placement Division. The aim here is to identify the right Division for you through single-player gameplay. This alternative placement method will lead to a better overall online experience for those players who are not used to playing head to head, and for those who prefer to learn the game through single-player before heading online.

FIFA 21 FUT Rivals
In FIFA 21 Squad Battles you can play against three kinds of opponents:

1) other squads from the FUT Community;
2) featured squads;
3) TOTW squad.

FIFA 21 Squad Battles
Your AI-controlled opponents in Squad Battles come from the real Squads used by other players in FIFA Ultimate Team (FUT). Specifically, Squads that were used by players when playing Squad Battles, Draft (Online and Offline), FUT Champions, and Division Rivals.
No. It only happens for the featured squads.
Four new teams are added in each round. Because this mode changes from minute to minute, you and your friends may get different squads.
When a set of opponents is provided, either at the start of a new Squad Battles competition or when you perform an Opponent Update, the game always provides one Squad from each of the three Squad difficulty buckets: Easy, Medium, and Hard.
Then it selects a fourth Squad from either the Easy or Medium buckets, with a 50% chance of the Squad coming from either bucket.

FIFA 21 Squad Battles
Each Squad in FUT has both a Team Rating value and a Chemistry value. When those values are added together, you end up with an Overall Squad Rating. Each of our difficulty buckets in Squad Battles contains a range of Overall Squad Ratings:

Easy = 0-140
Medium = 141-182
Hard = 183+

Featured Squad Battles are special matches where you can play against:

1) squads created by members of the FIFA and football community, such as real footballers, celebrities, or FIFA pro players;
2) the TOTW.

Not every weekly competition in Squad Battles will have a Featured Squad Battle.

Yes, it is. When opting to play Co-Op in Squad Battles both players will use one of their scored weekly matches. Based on the result of the game each participant will earn their score and coins for the match using the regular in-game calculations. If one player has run out of games that count for their weekly score, neither of you will continue to earn weekly score. That being said, both of you can still play the match to earn Coins & Skill Rating and make progress towards Objectives. You will know before starting the match if this applies as both players will receive a message warning if they are out of matches.

FIFA 21 Squad Battles
The competition refreshes every Monday, at 12:00 am (UTC+0).
You can see the complete calendar of FIFA 21 Squad Battles clicking here.

You can play unlimited matches but only 42 will count for your ranking: the first 40 against other squads from the FUT community and the last match against the featured squad and the TOTW.
This game mode is available since day 1. It can be played at any time, seven days a week. You are able to refresh 4 new squads whenever you want, until you hit your maximum of 10 refreshes for the weekly competition (up 40 games per week). While those first 10 refreshes are the only squads which will count towards your weekly competition standings, you will be able to continue to refresh and get new opponent squads to work on completing objectives or just for some fresh opponents to play.
The Opponent Update is how you refresh your list of available Opponent Squads. When you have played all the available Opponent Squads, you’ll have to refresh the list. To maximize your battle points, make sure to use all your Opponent Updates during the event. If you miss using an Opponent Update, you won’t get the maximum battle points for the event.

Be sure that you don’t press the ‘Opponent Update’ button before you play against all opponents available. As soon as you press R1/RB, the opponent’s list is refreshed and you no longer will be able to play those matches.
Each weekly competition will have a set of rewards available, with different rewards available for each tier. Once the weekly competition ends, and assuming that you had a score for that week, you will have earned a reward.

The more wins you get, the better rewards you get. However, there are a few things you can do to improve them even more: play in the highest difficulty levels; play as many matches as possible, including against the featured squad; play against the best opponents; and fight for as many skill bonus as possible (goals scored, shots on target, corners, clean sheets, etc).
You’ll get your rewards shortly after the event ends (usually it takes 5 minutes).

You will be able to claim your rewards shortly after the competition ends, either in-game or on FUT Web and the Companion App.
Generally, they are much worse than Weekend League and FUT Rivals rewards.
For each tier, there are different rewards. It can be different types of tradeable packs, FUT coins or both.
You can see here the complete list of rewards for FIFA 21 Squad Battles.
You will not receive any reward for that week.
They don’t expire. They will be waiting for you in your Ultimate Team.
Sure. You can save your rewards to be opened when the best special items are available in packs.
