Barker says AmaTuks will no longer be a team that play to survive, but a formidable side that will challenge for honours in the 2014/2015 campaign.
The Tshwane side had their second stint in the top tier last season and Barker said the departure of some of their key players was a strong factor in how they performed overall last season.
Tuks lost Aubrey Ngoma to Orlando Pirates, Bongani Zungu to Sundowns and Mame Niang to cross-town rivals Supersport United after their maiden stint in the PSL.
“It did sort of have an impact,” said Barker. “If you check, they were some of the best contributors to us finishing in the top-eight. But we have learnt a lot since then and we are hoping to improve on our game.
“The experience will come in handy. And I believe even some of our younger players are now starting to get a sense of what football at this level is like.”
Tuks have already started their efforts to strengthen the team. They have brought in defenders Vuyisile Ntombayithethi from Golden Arrows and Sfiso Nzimande from Witbank Spurs.
Barker added that the team were hoping to sign at least five players in total before the close of the transfer window. The longest- serving coach in the league also added he was still eyeing Ngoma, but said the decision is for Pirates to make.
