Last Tuesday, group H of the Champions League 2019/20 was decided, and the Dutch football (soccer) club Ajax ended up third place with as many as 10 points, failing to qualify for the next round since both Valencia and Chelsea have 11.
It's rather unlikely not to qualify with 11 points; that means two other teams need to have at least 11 points, for a total of 33 points. There are 12 matches in the group stage, for a total of 36 points, so there are at most three draws; this can only happen if the three teams beat the fourth team twice, and their six head-to-head matches end up in one win, one loss and two draws for each team; each team ends up with 11 points, but goals fore/against may make a distinction here.
Similarly, there's only one scenario where a team with 12 points doesn't qualify: if two other teams have 12 points, when all matches are decisive, they all beat the fourth team and they all win exactly two out of four head-to-head matches.
In the history of the Champions League, have any other teams failed to qualify for the next round (in a group of 4, where the top 2 qualify) with as much as 10 points? What about other (high level) football competitions?
