Celtic are well on course to win the Scottish Premiership title this season.
The Bhoys are on course to win the Scottish Premiership title, yet there is still a great amount of frustration around Parkhead at the moment.
Celtic have not entirely convinced this term, but Lustig does feel that some of the stick they have received has been unwarranted.
“We have not been satisfied with most of the season,” said Lustig. “Sometimes we have felt the criticism has been a bit harsh, other times we can agree.
“But if we can have a strong finish in the league and cup then maybe it will not look bad at all. We are in a good position in the league with eight points clear and we have a chance in the cup.”
Celtic’s failure in Europe, for the second season running, has caused particular annoyance at Parkead.
The Bhoys failed to qualify for the Champions League, and they then struggled to make an impression in the Europa League group stage.
Celtic have also put in some poor performances in domestic action this term, and they have not looked entirely convincing in the league.
The pressure is now on the team ahead of the Old-Firm derby clash against Rangers at the weekend.
Celtic head into the match against their bitter rivals as heavy favourites, and defeat in that fixture would only lead to further criticism being directed at manager Ronny Deila and the players.
