Celtic manager Ronny Deila has called for referees to explain their decisions post-match following his team's controversial William Hill Scottish Cup semi-final defeat by Inverness.
Referee Steven McLean failed to penalise Josh Meekings after the Caley Thistle defender used an arm to block a header by Leigh Griffiths.
Meekings was offered a one-game suspension by the SFA, but won his appeal after an independent three-person judicial panel tribunal ruled the case should not have been brought in the first place.
Ahead of tomorrow's trip to Dundee United, Deila was asked if referees should be allowed to explain their decisions.
"Why not?" he said. "What is the problem? To be open and honest is important and then we can stop talking about this for weeks. If I was the referee after that match and he knew what happened, I would say 'I didn't see it. I am very very, sorry, I should have done better' and what more can anyone say?"
Rangers boss Stuart McCall has warned his side to be on their guard when Falkirk visit Ibrox today.
"They don't lose many goals so we may have to be patient. We have had a couple of decent results against them but they have capable players and we will need to be at our best."
