Murray knows what to expect: Federer

INDIAN WELLS, California: Britain's Andy Murray knows what he must do to stretch his winning streak over 13-time grand slam champion Roger Federer - the Swiss, though, is still unsure how to stop his nemesis.

World No 2 Roger Federer has lost to the Scot five times in seven career meetings, including their last three encounters, and next meets him in the semifinals of the ATP event at Indian Wells.
