Serena Williams and Carlos Alcaraz are the main attraction in this tournament and they did not disappoint in the first round.

Belinda Bencic and Flavio Cobolli are looking to play spoiler in the last eight. They came through a massive test in round one, making a mockery of their tag as underdogs by beating Taylor Townsend and Alexander Zverev in straight sets.

Momentum is with them and their ability to strike winners from all over the court may just give them the edge. Therefore, back Williams and Alcaraz to triumph in a potential thriller.
