Celtic boss Ange Postecoglou has taken full responsibility after his team drew 1-1 against Midtjylland in the Champions League qualifiers.
The Scottish giants are hoping to reach the group stages of the competition for the first time in several seasons.
A total of 9,000 fans were in Celtic Park for the game, but the home side had to settle for a draw in a breathless game. The second leg is in Denmark on July 28th.
Celtic manager Postecoglou said after the game: "I don't think we will ever be as badly prepared as we were tonight going into such an important game and that's on me.
"I haven't done a great job so far because with the disruptions we've had, we haven't been able to bring the players in.
"The players didn't look for excuses. They put in a solid shift and I'm just disappointed they didn't get the rewards for what I thought was an outstanding performance."
