Andy Murray is taking on Roger Federer for the second time in a week on Friday after beating Sergiy Stakhovsky in the quarter-finals of the Qatar Open.
The defending champion wasn't given an easy ride by the Ukranian, but he eased to a 6-4 6-2 victory as Stakhovsky tired towards the end of the first set.
Now he's concentrating on winning his semi-final clash with Federer.
Murray's got a great record against the Swiss star, having won four of the six matches they've played together.
And he's quietly confident of netting his fifth victory over the world number two.
"I am happy with the way I am playing now," he said. "I don't see any reason to doubt my chances in the semi-final."
