Juventus GM Beppe Marotta says Wolfsburg striker Edin Dzeko is their top target.
Juve have also been chasing CSKA Moscow winger Milos Krasic.
"If we had to choose between Krasic and Dzeko because of the non-EU quotas then we would go for the striker [Dzeko]," he said.
"But it is a difficult transfer because the Germans will not give in to their high demands, but we will continue relying on the player's will."
