UEFA will hope that fair play prevails on the final Euro 2024 matchday in Group E on Wednesday with its unprecedented situation.
Romania (3-2 goals), Belgium (2-1), Slovakia (2-2) and Ukraine (2-4) are all tied on three points but for Romania and Slovakia a draw in their match would send both into the last 16, regardless of the outcome of Belgium v Ukraine.
The ruling body will not want a repeat of the infamous 1982 World Cup match between West Germany and Austria, where both teams effectively stopped playing after the Germans went 1-0 up. That scoreline saw both through at the expense of Algeria who had played their final match earlier.
To avoid similar scenarios final group matches at big events are nowadays played at the same time.
But the Euro format, in which four third place finishers join the top two from the six groups in the last 16, coupled with the unprecedented Group F standings, could lead to concerns.
A draw between Romania and Slovakia would give both four points which is more than the third-place finishers from groups A (Hungary - 3) and B (Croatia - 2).
They will finish second and third if they draw and Belgium v Ukraine has a winner, and two draws would also see them through because Ukraine would remain last on goal difference in that case.
This means that only Ukraine is in a must-win situation to advance without the help of others. The three others can however also not afford defeat.
