Kairat Almaty boss Rafael Urakhtin blasted his players for conceding 'childish goals' ahead of facing Celtic in the Champions League after an extraordinary collapse.
Celtic will face the Kazakhstan dark horses on Wednesday with a £40 million prize at stake for reaching the league stages of the competition.
But Kairat suffered a disastrous warm-up for the game when they blew a two-goal lead at home to Yelimay Semey to lose 3-2.
It was only Kairat's third league defeat in 20 games in their season and Urakhtin wasn't impressed ahead of their marathon journey to Glasgow.

He said: "We have no time to grieve about this result because we are preparing for a very important match in Scotland and have a long journey to make.
"But it was a disappointing defeat for us.
"We were a long way from our best defensively and we conceded childish goals.
"If you are fighting for the league title, you cannot concede goals like this.
"The players actually carried out the instructions well....except for losing those goals.
"We knew they would be difficult to break down, but we managed to do it....and then we conceded stupid goals.
"When my players perform well, I praise them, but when we make such basic mistakes like we did, then I have to point it out."
