Strachan felt his side should have been awarded a penalty by referee Lee Mason for Fabricio Coloccini's second-minute challenge on Scott McDonald.
Gordon Strachan: "We should have had a penalty in the first two minutes, and the referee just to make it up, allowed us to get away with a free-kick 30 seconds after it.
"If you are going to make a decision, referee, don't try to even it up. It's not right, we don't want that.
"Be brave and stand by your decisions."
