Aberdeen manager Derek McInnes has expressed his disappointment with Mikael Lustig after the experienced Celtic star appeared to goad Lewis Ferguson shortly before the full-time whistle.
Several Aberdeen first-team stars confronted the Swedish international after the incident, which occurred mere seconds before referee Andrew Dallas blew for full-time.
Celtic won the match thanks to a solitary goal, scored by Ryan Christie in first-half stoppage time.
“I just felt it was a bit unnecessary,” explained McInnes. “He [Lustig] is a grown man and experienced international, running into Lewis’ face and laughing and all the rest of it.
“We’ve seen players from other clubs being yellow carded for that and a lot made of it. It was just disappointing and I was making the point that he was trying to goad young Lewis who kept his temperament well.
“If he (Lustig) was trying to get a reaction from Lewis, thankfully young Lewis was the grown up in the whole situation.”
