The results of the group phase are still partially undefined (null). e.g

 {
          "num": 32,
          "date": "2021-06-15",
          "team1": {
            "name": "France",
            "code": "FRA"
          },
          "team2": {
            "name": "Germany",
            "code": "GER"
          },
          "score1": null,
          "score2": null,
          "score1i": null,
          "score2i": null,
          "group": "Group F"
        }
