Celtic manager Gordon Strachan was happy with an improved performance from his side against Falkirk.
"We're back in terms of freshness and imagination," he told BBC Sport after the 2-1 win. "We looked dangerous every time we went forward.
"The game should have been over and done with well before Falkirk scored and we were a little nervy at the end.
"But I'm pleased with the display and it's given me a few things to think about before the weekend."
