Atletico Madrid star Sergio Aguero remains Juve's top summer target while Bayer Leverkusen midfielder Arturo Vidal and Roma forward Mirko Vucinic are also on the Bianconeri's radar.

"We want to spend our money well," Marotta told Turin-based newspaper Tuttosport.

"You must hit at the right time. There is no deadline.

"We have clear ideas and if someone prises Aguero away from us, it will only be down to the fact that the club in question has made a financial offer that is out of our reach.

"We have the right budget to increase the quality of our team but certain of our signings are linked with the departure of some of our players.

"Aguero, Vidal and Vucinic would enhance the quality of the team.

"I can confirm that we will place a big bulk of our transfer budget in just one player."

Juve finished seventh in Serie A and missed out on European football next season.
