If this is about tie-breaks in a tournament or bracket , the answer depends on the event’s specific rules, but in many formats the head-to-head result, goal/map record, or Sonneborn-Berger/tie-break points decides who advances and who is knocked out.

For a Belgium vs. Senegal-style matchup, that usually means:

  • If one team has the better direct result, that team stays in.
  • If the teams are still level, the competition’s published tie-break rule set decides it.
  • If the format does not break the tie cleanly, both can advance or the next tiebreak metric is used.

So the real answer is: the team that loses the relevant tiebreak criteria gets knocked out, not automatically “Sen” or “Bel.” If you share the exact tournament or standings format, I can tell you which one goes through.
