The new boss of Starbucks says he will overhaul the global coffee chain's menu as the company continues to see its sales slide. Brian Niccol also announced that he was suspending the firm's financial forecasts for the coming year due to the "current state of the business".

Starbucks has been under pressure for awhile. Following two quarters of consecutive declines in sales and a stock price that dropped nearly 30 percent in six months, the board of directors decided this summer to abruptly replace its then-chief executive, Laxman Narasimhan.

The company's same-store sales slid for the third consecutive quarter, fueled by a 10% tumble in traffic to its North American stores.
