Juventus coach Maurizio Sarri would not confirm whether he will continue to use Cristiano Ronaldo, Paulo Dybala and Gonzalo Higuain as a front three against Cagliari, but he warned of the threat of the opposition midfield.
Sarri bowed to pressure by using Ronaldo, Dybala and Higuain together in attack ahead of the mid-season break.
Although the star trio initially impressed in wins over Udinese and Sampdoria, they then started the 3-1 Supercoppa Italiana defeat to Lazio.
Sarri insisted at the time that loss was not due to his front line, yet speaking ahead of a return to Serie A action against Cagliari, he would not commit to sticking with the system.
A talented Cagliari side boasting the likes of Radja Nainggolan, Nahitan Nandez and Marko Rog could see Sarri select Aaron Ramsey instead.
"We'll see tomorrow," he told a Sunday news conference of his line-up. "Ramsey also seems to be growing, so we will have to decide.
"We will need to take a lot of care. The Cagliari midfielders can start strong attacks, so we will need great balance on our part, especially in midfield.
"When you concede a lot of goals [before Christmas], you often place the blame on the defenders. But that's not always the case.
"In my opinion, the right protection has not been given to the defence. That's why we have been working on the movements of the midfielders."
Douglas Costa is still regaining fitness, but centre-back Matthijs de Ligt could be handed a recall, having not started since a league defeat to Lazio on December 7.
"He had a complicated period, with shoulder and adductor problems," Sarri added of the Dutchman. "He is very young, he rested because he had small problems, and [Merih] Demiral has grown a lot.
"He seems to be recovering, so we'll see for tomorrow."
Juventus this week completed the signing of Dejan Kulusevski from Atalanta for an initial €35million, although he remains on loan at Parma.
Sarri said: "[Kulusevski] is a great prospect and it is important that the club is attentive to these young players and gets there first.
"There were no conditions [possible] where he could be available now."
