The Polish giants are now seemingly out of avenues regarding their protest against their punishment.
Celtic boss Ronny Deila certainly took some time to settle in at the club. The Norwegian struggled in early months and that showed in the Champions League qualifying rounds.
They were thrashed by Legia Warsaw in the Champions League play-off round at the start of the season, losing 6-1 on aggregate. But the Polish side played Bartosz Bereszynski in the final minutes of the second leg, despite him being suspended.
Celtic were therefore awarded a 3-0 win, putting them through to the next round on away goals.
Celtic went on to lose their Champions League fight at the next stage, dumped out by Slovenian outfit NK Maribor. Legia however have only just finished their battle.
They originally appealed the decision, but failed to gain re-entry. They have since been fighting for compensation pertaining to lost revenue from a lack of Champions League football.
Today however, the story came to an end, nine months since they played the second leg in Glasgow in August last year. The Court for Arbitration for Sport have rejected their latest appeal and they are now essentially out of explorable avenues.
For Legia however there is some comfort. They currently top the Polish Ekstraklasa by two points from Lech Poznan - meaning they are on course for another shot at the Champions League next season.
What price another meeting with Celtic?
