Table: team_players

| id | team_id | player_id |
----------------------------
  1    1         1
  2    1         2
  3    2         1
  4    2         2
  5    2         3


I have 2 player_ids, 1 and 2.
I want a query that tells me if that team already exists. (team_id 1 in the example above)
Note that the same players can be on another team with more players (with player 3).
