Manager Ronny Deila says it is "stupid" that Celtic have to negotiate three qualifying rounds just to make the group stages of the Champions League.
Thanks to Scotland's poor club ranking, Celtic must beat Icelandic side KR Reykjavik and two other teams to make the group phase.
"Celtic have been fighting for many years with the best teams in Europe," said Norwegian Deila.
"It is stupid the Scottish coefficient is not regarded as good enough."
“It's very unfair that going to the last 16, as we did two years ago, is not going to be recognised”

The Scottish champions, who reached the last 16 in 2013, are aiming for a third consecutive season in the group phase.
"I knew before I came here that we had three qualifying rounds," added Deila, who was appointed on 6 June.
"That's wrong because you have to take into consideration the club, not the country.
"We need the biggest clubs in the Champions League, who have deserved it.
“Celtic don’t deserve to have three rounds before going into the Champions League groups.
“It’s very unfair that going to the last 16, as we did two years ago, is not going to be recognised.”
Asked if Celtic deserve more respect from UEFA, the Norwegian answered: “Yes, I think so. This is a very big club with fantastic history.
“Celtic in the Champions League sounds good, it sounds like a good relationship.”
