Juventus GM Beppe Marotta says missing out on the title this season would be a "sporting failure".
Juve are currently trailing Serie A leaders Napoli.
Marotta said: “Transfers? We have no deep problems, but we have to look ahead, knowing that we need to be competitive and seize any opportunities that the market offers us.
“It's not easy, and when you have to sign a player for Juventus. It's not easy to find them.
“It's also true that we need to reflect on this squad, in terms of age, but we also realise that we have great professionals.
“In my role for Juventus, my objective is to get to the top, and this Champions League is almost an obsession for us.
“We managed to reach two Finals, but we couldn't lift the trophy. This must be a reason to get to Kiev, and maybe with some luck we can lift the trophy.
“Scudetto? Not winning it would be a sporting failure. Given the quality of our squad, we believe that we must be candidates to win it again."
