Juventus director Giuseppe Marotta has set out the plan to reform and recast the squad, admitting he is still following Wolfsburg striker Edin Dzeko and Milos Krasic of CSKA Moscow.
Negotiations for both players have come unstuck over the transfer fees. Krasic pleaded via his agent Marko Nateletic on Tuesday that he was still keen on Juventus, whereas Dzeko has made it clear he will be leaving his German employers.
And Marotta is ready to fold a move together for both men if he can convince the players' respective clubs into yielding.
"We need four reinforcements, but two are priority - a left-back and a right winger," he told Il Corriere dello Sport.
"Krasic? Absolutely yes. We are following him with attention, but we have to remember in his case that he is a non-EU player."
The transfer trail for Dzeko appeared to have gone cold after Wolfsburg demanded €40 million.
But Marotta feels he has wide-ranging scope to deliver a move that will be tolerable on club funds.
"He is a dream that will not go away and we will continue to follow him until it becomes impossible, but we are aware of the big difficulties," he added.
"Wolfsburg have set a high price and the competition for him have big resources."
Diego has been linked with both Wolfsburg and Hamburg. Tuttosport claim both clubs are offering €20m. And Marotta maintained no player is invaluable.
"Diego and Melo occupy a good position in the group, but if big offers come then we will evaluate them," he said.
