The Hoops were stunned by Shakhter in the first leg of their Champions League playoff qualifier and now the Swedish defender is determined to atone for that subpar performance in Glasgow on Wednesday.
"Of course it is a very bad result," he said.
"We wanted to come here and get the right result but we did not do things the way we had wanted to.
"I would say we were the better team and created most of the chances in the game but we simply were not good enough in our own box or theirs.
"We knew before the game that using the long throw was a tactic of theirs and something that would allow them to bring their bigger players up from the back.
"Overall, we made many chances and should have scored one or two goals.
"When we get them home to Celtic Park, we need to do things the right way at both ends of the pitch.
"For a start, we need to be better at defending the situations which Shakhter use to their advantage and we also need to be better in attack and score some goals.
"It's going to be really hard but we know it is only the halfway point."
