British hopes of Wimbledon success have been tempered by the absence of Andy Murray, and the last three remaining home players in the main singles events are all in action on Thursday.

It is a day loaded with eye-catching matches and storylines.

Here Press Association Sport looks at four aspects to look for on the fourth day of the championships.

Edmund and Djokovic on collision course

British number one Kyle Edmund and Serbia’s three-time Wimbledon champion Novak Djokovic will go head to head on Saturday, as long as both win on Thursday. The prospect is tantalising and it is hard to see Djokovic having any trouble with Argentinian left-hander Horacio Zeballos, and providing that theory holds true it would leave Edmund to take out little-known American Bradley Klahn to get the weekend match on. It should be well within his scope, but Edmund has never reached the third round at Wimbledon before, meaning the 23-year-old is edging towards unexplored territory.

Is Kyrgios a changed man?

The Australian has made headlines for his mischievous, sometimes misbehaving ways in the past at Wimbledon and elsewhere. But he was good as gold in his opener on Tuesday, a four-set win over Denis Istomin. On Thursday he tackles Dutchman Robin Haase, a player he beat in their only previous meeting three years ago in Estoril. Kyrgios has the tennis tools to make a huge impact on grass, and might be wising up to the need to adopt the right attitude too.

First big test for Konta

That wimbledon sweat 💥👊🏻

Dominika Cibulkova is a player few seeds would especially relish facing at Wimbledon. The hard-hitting Slovakian can name Caroline Wozniacki, Agnieszka Radwanska and Eugenie Bouchard among her past victims at the championships, and she has a point to prove after being knocked out of the seedings when Wimbledon officials elected to promote Serena Williams into the top-32 pack. Johanna Konta will have her work cut out, and if the British number one comes through that will be a highly positive sign of what she might achieve this fortnight. Fellow Briton Katie Boulter, meanwhile, faces a tall order against Japan’s brilliant 20-year-old Naomi Osaka.

Junior-senior

Ashleigh Barty and Bouchard both already have Wimbledon titles after winning the girls’ singles in 2011 and 2012 respectively. Bouchard looked the most likely to step up and claim slam trophy success at senior level, only to lose to Petra Kvitova in the 2014 Wimbledon women’s final. The Canadian’s decline in fortunes and ranking since – from a high of fifth to her current 188th – has coincided with Barty going the other way. Australian Barty has soared from outside the top 250 at the start of last year to her current status as world number 17. On Thursday they go head to head. It could be rather special.
