Big four headline just another 'manic Monday'

Novak Djokovic, Roger Federer, Stan Wawrinka and Andy Murray remain on course for the Wimbledon semifinals ahead of 'manic Monday' when the last-16 takes place.

Six of the top 10 seeds are safely into the business end of the tournament after a first week which saw seventh seed Milos Raonic and 10th-seeded Rafael Nadal defeated on court.

Fifth seed Kei Nishikori withdrew before the second round with a calf injury while eighth-seeded David Ferrer pulled out before the first round.
