THISTLE frontman Tommy Stewart insists the Jags will use Saturday's cup humbling against third division Berwick Rangers to ensure their first division campaign gets off to a flier.
The Jags were dumped out of the Scottish Communities League Cup by gutsy Berwick despite taking a first half lead in a performance which boss Jackie McNamara described as "worrying".
Not only was the result a blow to Thistle's coffers as they missed out on a potential money-spinning clash with an SPL side in the latter rounds but it also put a huge dent in the air of optimism floating around Maryhill ahead of this weekend's SFL kick-off.
Stewart accepts he and his team mates were guilty of complacency after taking an early lead.
But he promises Jags fans there will be no more mentality problems when Dundee visit Firhill to begin the league season on Saturday.
The 24-year-old Irishman said: "We let ourselves and the staff down on Saturday.
"We put a lot of hard work in in pre-season so to come away with a performance like that is unacceptable.
"There was too much complacency. We were 1-0 up and could have gone on to score a couple more but for some reason we switched off and gave them the incentive and belief and they capitalised on that.
"The only positive now is that we will be really switched on for Saturday. There will be no mentality problems."
One former Dundee player who is set to join Thistle for training at least is ex-Scotland winger Neil McCann.
The 36-year-old will train on Thursday as McNamara looks to add experience to his young squad.
