The big talking points for day three at Wimbledon

Wimbledon is heading into the second round after an action-packed opening two days.

There have been shocks, drama and routine wins as the All England Club has seen glorious weather.

Here are four things to look out for on day three.

All eyes Swan one you, Katie

Being Serena

Serena Williams made her long-awaited Wimbledon comeback on Monday and got past Arantxa Rus without being at her best. She admitted to still getting her bearings after missing the tournament last year while pregnant, but she is returning to a place she knows like no other after being scheduled to play Viktoriya Tomova on Centre Court. She has not played there since the 2016 final and all eyes will be on how she pulls up for a second match in three days and whether it will be business as usual.

Federer’s Centre Court residency

It is not surprising that Roger Federer is back on Centre Court. While most high-profile players generally play at least one game on Court One, Federer played exclusively on the main show court on his way to the 2017 title and his second-round clash against Lukas Lacko is also there. A bigger question might be who will be the next person to take a set off him at Wimbledon after winning his last eight matches here without dropping one.
