London: Swiss Roger Federer warned his rivals not to write him off yet after a Wimbledon final defeat that left the Swiss star without a major title for three years.

Federer's bid for a first Grand Slam crown since he last won Wimbledon in 2012 was shattered as No 1 Novak Djokovic clinched a 7-6 (7/1), 6-7 (10/12), 6-4, 6-3 victory on Sunday.
