Monday at Wimbledon: Kyrgios, Halep and Nadal on Centre Court

After the Middle Sunday action at Wimbledon the fourth rounds of the men's and ladies' singles will be completed on Monday.

There will not be the frantic 'Manic Monday' action of the past but there still promises to be plenty of fireworks on the main show courts.

First up on Centre Court is a clash between two unseeded players as Nick Kyrgios takes on American Brandon Nakashima.

Maverick Australian Kyrgios was involved in a heated third-round match on Saturday as he saw off fourth-seed Stefanos Tsitsipas, who branded him an "evil bully" afterwards, and he also made the headlines after defeating Filip Krajinovic in the second round when he described himself as one the "most important people" in tennis.

"I'm extremely confident in myself. All the challenges I've overcome in my life. Proud to be up here and doing it my own way. Being able to produce tennis like that at Wimbledon, it's a dream come true for any tennis player," said the 2014 quarter-finalist, who was fined $10,000 for spitting towards a fan during his first-round match.

"Well, I didn't want to remind people that I'm good; I know that I'm good," he continued. "I just feel like people just don't give me the respect sometimes because of other things that I do."

Kyrgios now has another chance to demonstrate his ability as a tennis player against Nakashima who eased past Colombian Daniel Galan in straight sets in the last round after beating 13th-seed Denis Shapovalov in the second round.

Second up on Centre Court will be 2019 champion Simona Halep against fourth seed Paula Badosa of Spain who overcame Petra Kvitova in the last round.

Neither of the players has dropped a set in the tournament so far and a hard-fought contest looks on the cards.
