Benfica's last-ditch winner against Anderlecht, combined with Edinson Cavani's winner at the Parc des Princes, cost the Spanish coach's side qualification for the knockout stages.Olympiakos boss Michel claimed that "there is no justice in football" after his team went from being guaranteed a spot in the Champions League last 16 to having its hopes left hanging in the balance after losing 2-1 to Paris Saint-Germain.
Qualification from Group C looked assured as the Greeks entered stoppage-time at the Parc des Princes level at one goal apiece with 10-man PSG, with Kostas Manolas having cancelled out Zlatan Ibrahimovic's opener.
However, Edinson Cavani scored a late winner for the home side and, to add to Olympiakos' woes, third-placed Benfica drew level on points with it thanks to Rodrigo's last-gasp winner at Anderlecht.
"It's like that in football: there is no justice or morality," Michel told reporters after the game. "We must face reality. "We did not get a sufficient result to qualify tonight and we now must do so against Anderlecht [on matchday six]. We accept the result, but if you look at the first five games, I think we deserve to qualify.
"I think when we equalized, PSG really expected it to finish [at 1-1]. They have great players, it is undeniable, but I think even they do not know how they were able to score the second goal.
"We gave too much respect to PSG. We should have been more daring."
Olympiakos has a better head-to-head record against Benfica so, in order to progress, it only has to equal the Portuguese side's result against PSG in a fortnight's time when it faces Anderlecht.
