Input: The inquest will be long, weary and painful. Yet the reasons Celtic suffered a second successive Champions League exit under Ronny Deila were not hard to find. On a night when they needed discipline, calm and composure, Scotland's champions contrived to make a pig's ear of it. Malmo not only had the mouth. They also had the trousers.

The Achilles' heel is clear, brutally exposed once more to the naked eye here.Celtic failed to reach the lucrative group stage of the Champions League after losing in SwedenMarkus Rosenberg opened the scoring for the home side with a header in the first halfCeltic's Leigh Griffiths was fortunate not to see red for appearing to knee an opposition player in the privatesThe visitors had a goal disallowed when Nir Biton found the net but the referee incorrectly ruled a handballFelipe Carvalho added a second 10 minutes after the break to double Malmo's advantage
