Wolverhampton Wanderers were guilty of making some costly errors during the early part of the season.
Wolves were guilty of giving away goals to opposition teams in the early part of the campaign, with Carl Ikeme and Emilio Martinez making a number of mistakes.
It was a worrying spell for the club, as they struggled to live up to expectations, but it appears as though they have turned the corner now, and Jackett believes that his squad have restored dented belief.
"We had some mistakes, some goalkeeping mistakes early in the season which affected our results and confidence," he said.
“Sako going and Nouha’s injury have both been well documented but we feel we are settling down.
“Now it is all about these next four games, making sure we get a good return.”
Martinez is currently Wolves' number one choice between the sticks, and the Arsenal loanee is growing into his role.
Although he made a shaky start to life at Molineux, he has now played nine times and his most recent appearances have been excellent.
The Argentine stopper has kept three clean sheets in his last four league matches, and Wolves' form has improved hugely due to their secure backline.
Wolves are unbeaten in their last four Championship matches, but they face a very tough test against promotion-chasing Derby County at the weekend.
