Terengganu are currently third in the Malaysia Super League, three points off leaders Kelantan, and are fresh off the back of a 1-0 win over Song Lam Nghe An in the AFC Cup.
While confidence within the camp is currently high, Turtles coach Mat Zan Mat Aris is slightly concerned some of his charges may be starting to tire.
"My men played with great discipline and were rewarded with the valuable win [against Song Lam]," Mat Zan told The Star. "They played out on the field and stuck to the game plan.
"Our only worry is their fitness given the hectic schedule of the past week. The game on Saturday will mean that the players will have played three matches in eight days.
"I will assess their fitness before deciding the starting line-up."
Elsewhere on Saturday, high-flying LIONSXII take on second-division Betaria FC buoyed by Tuesday's 3-1 win over Felda United. All eyes will once again be captain Shahril Ishak, who is the second joint-top scorer in the league on six goals.
