The race for football's greatest prize is now down to just 32 teams.
Having watched the playoffs and qualifying rounds take place, the UEFA Champions League group stage is now seemingly ready to begin. We know which teams will battle it out, and while we don't yet know the groups or how those matches will play out, we do know which teams and players to watch for.
And in terms of players worth watching, the list is endless.
Even when we try to just look at young players, the number of stars who could make the list is remarkable—so we've tried to cut down that list even further.

Secondly, only one player per team made this list. That allows us to gain a bit of a wider view on the Champions League as a whole, rather than missing out on several teams and key players as a result.
