Juventus coach Max Allegri says he hasn't discussed the January market with the club's football directors.
It's been suggested Juve can launch a major push for the Scudetto if they make the right signings in January.
But Allegri says: "We haven't talked about it with the club, at the moment the most important thing is a group of players cohesive, united.
"We are working to become even stronger. The strength of this group are those who have found less space because during training they keep the intensity very high.
"This is the most important thing, then in the future we don't know what can happen. Football must be lived with balance and tomorrow we must have respect for Cagliari."
