For representing a relationship which design is better?

I am trying to model Team and Players relationship in terms of writable code following OOP.

Let's say I have a class Team and Player

For representing the relationship between both, which option is better & why?

What are the pros & cons of each?

Option A

class Team {

// inside team class
  List<Player> players;

}

Option B

//separate class
class TeamPlayers {
  Team team;
  List<Player> players;
}
