It could be used with several people or a single player.
You can't keep your eye on every single player in the league.
This year though, not a single player can be called the big favorite.
What, the single player was nothing to write home about?
I like single player 95% of the time so this is interesting.
Not a single player was really an issue for him in the past.
In single player, orders can be given to the rest of the team.
The club began the season having not signed a single player.
Often used for training, or when the single player is much better than the other two.
Once for the single player and again to play online.
