The Pittodrie boss said: “It is important that everybody keeps calm and trusts our experience, I am sure we can get the results we want.
“I think there has been a hangover from the supporters after the Cup Final and, potentially, from ourselves.
“We have told the players we can’t allow that. Whether we had won or lost the Final, it was important to fully concentrate on the next part of the season and get some league wins.
“I believe we have had some decent performances since Hampden, including the performances at Ibrox against Rangers and at Ross County on Saturday. We had a very strong performance in the 5-1 win against Kilmarnock at home, but we huffed and puffed in the 0-0 draw with St Johnstone.
“We didn’t do enough to win that game, but in the couple of matches we lost the performances weren’t far away from what we expected.
“It is important the players remain confident. We have a good set of lads here and we have never thought we were this or that.
“But we do feel we are a strong collective unit and we will prove that over the course of the season.”
Looking ahead to tomorrow night’s game at Fir Park, McInnes added: “Motherwell tend to play with a front three and normally score goals, so we need to make sure we limit their opportunities.
“At the same time, we need to be good enough to win the match.”
