It all started so well for the home side. They were awarded a penalty, albeit a dubious one, by referee Alan Newlands which Josh Mullin made sure to captialise on.
They were only able to hold onto their lead for six minutes after Niall McGinn scored a wonderful free kick to level the match. Aberdeen pressed and harried the Staggies and eventually got their reward.
Ryan Hedges put them in front with another free kick before Andy Considine finished the match with a brilliant curled effort.
Speaking after the game, Ferguson lamented his side’s errors at the Global Energy Stadium.
He said: “We felt we had a decent gameplan today. We tried to go with two wide players and two strikers on the pitch, whilst remaining tight and compact out of possession.
“We are contributing to the goals we are losing and that’s the frustrating thing in the dressing room. You come up against Aberdeen and they know how to win games and put you under pressure.
“We felt we frustrated Aberdeen in some bits whilst offering something in attack ourselves. The two free kicks we feel we played a part in conceding those goals and also the third one we are kicking ourselves.
“We need to come to terms with that we aren’t going to get away with that in the Premiership. We’ll go all-out to make sure we stop it.”
