Order of Play, Day 5 - Maria Sharapova and Caroline Wozniacki clash, Roger Federer, Nadal in action

Yes, Roger Federer and Rafael Nadal are both in action - but two former world number ones face off against each other in what should be a spellbinding encounter. The 2018 champion takes on the defending champion - and both are in brilliant form coming into it, with Sharapova dropping just three games in the previous two rounds combined.

Difficult to pick one that will go against seedings - unless you count the unseeded Tomas Berdych, down the rankings due to his back injury last year, who's been looking very good indeed here and plays 18th seed Diego Schwartzman. The Argentine might find himself in trouble.

None in the singles - cast your eyes out to the doubles courts. Dominic Inglot plays alongside Franko Skugor to take on Taro Daniel and John Millman, and Harriet Dart partners Anett Kontaveit against 13th seeds Kirsten Flipkens and Johanna Larsson.
