Juventus chief Beppe Marotta says they'll always be wary of overspending in the transfer market.

Juve have been clever so far this summer after landing strikers Carlos Tevez and Fernando Llorente, along with defender Angelo Ogbonna.

"We have to pay attention to our finances," Marotta said. "Our model is this: we want to remain the top team in Italy and be highly competitive in Europe even if it is increasingly hard to compete in the international transfer market these days."
