Managers on UCL Fantasy, presented by PlayStation, have the chance to boost their matchday totals by making substitutions during a matchday – allowing low-scoring players to be substituted out in favour of those whose team are yet to play.
The 15-player squad – incorporating two goalkeepers, five defenders, five midfielders and three forwards – gives Fantasy managers flexibility to change players and formation in search of bigger returns. Just as the captaincy can be switched from one player to another whose team feature later in the matchday – for example, a captain in action on a Tuesday can make way for a new captain who does not play until Wednesday – the same applies to the squad as a whole.
That allows managers the freedom to switch their teams, which means it's sensible to start the matchday with players who are in action on Tuesday. Then, should any of your initial line-up not score as highly as you hoped, you still have the chance to substitute them out in favour of players in action on Wednesday.
Importantly, you can also switch formations when making substitutions. So if, for example, your team initially lines up in a 5-3-2 but two of your defenders return low totals on Tuesday, managers are able to replace defenders with midfielders or forwards – in this example, the final formation once substitutions have taken place might be a 3-4-3.
Note that your formation must have a minimum of three defenders, two midfielders and one forward.
There are some restrictions to remember, however:
• You can't sub players into your starting 11 who have already played in that matchday, and nor can you change to a captain who has already played in that matchday.
• Once you confirm your subs or change of captain, those changes cannot be reversed.
