Roger Federer threatened a massacre before easing through to the quarter-finals of Wimbledon for the 16th time.

The eight-time champion needed only 16 minutes to win the first set against France's Adrian Mannarino. He could not sustain that pace but was never seriously threatened in a 6-0 7-5 6-4 victory that sets up a meeting with either Gael Monfils or Kevin Anderson.

The result extended Federer's run of consecutive sets won at Wimbledon to 32, two short of his career best from 2005-06, while he has not dropped serve since the semi-finals last year.
