MILAN, June 1 (Reuters) - Fiat Chrysler Automobiles Chief Executive Sergio Marchionne said on Sunday a good performance of the U.S. operations was crucial for the success of the group's recently announced business plan.

"The execution of (Fiat Chrysler Automobiles) business plan announced on May 6 depends from the fact that U.S. operations perform well," said CEO Marchionne, while speaking at a business conference in the town of Trento in northern Italy.

"We need the cash coming from U.S. operations to fund the group's strategy in Europe," Marchionne said.
