Rafael Nadal insists he was worthy of his place on Centre Court ahead of women's top seed Ashleigh Barty on manic Monday at Wimbledon.

The Spaniard breezed through to the quarter-finals with victory over Joao Sousa while Barty was a surprise loser to Alison Riske on Court Two.

The second Monday is a notoriously difficult day for the tournament organisers as all last-16 games in both the men's and the women's draws have to be scheduled.

Novak Djokovic's title defence is still yet to come under serious threat as he eased into the last eight for the 11th time.

The world number one breezed past French rookie Ugo Humbert in straight sets, 6-3 6-2 6-3, on Court One to set up a meeting with David Goffin in the quarter-final.

It is the 45th time he has reached this stage of a grand slam – only Roger Federer has achieved more – and few would back against him claiming a fourth SW19 crown on Sunday.

David Goffin has always believed he has had the game to be a success at Wimbledon after posting his best-ever run at the All England Club.

Roberto Bautista Agut is also enjoying his best performance thanks to a brisk straight-sets victory over Benoit Paire.

The Spaniard ousted the erratic Frenchman, who later said he was playing with an abdominal tear, 6-3 7-5 6-2.

Sam Querrey is back in the last eight of Wimbledon after a four-set victory against his compatriot Tennys Sandgren.

Querrey, who reached the semi-final in 2017, won 6-4 6-7 (7) 7-6 (3) 7-6 (5).
