Serena Williams takes on Angelique Kerber in the women's final at Wimbledon on Saturday and we look at the key talking points ahead of the big showdown.
Return to sender
Williams has fired down more unreturned first serves than any other player in the women's draw at these championships, with 50 per cent of the balls she has landed in not coming back to her. Kerber has to find a way to put more balls back into play, and after winning just five of 43 points when Williams landed her first serve in their final two years ago that is an area where the German must significantly improve.
Fight fire with fire
It is a no-contest in terms of serving strength, but Kerber can keep the pressure on powerhouse Williams by landing a high percentage of her first deliveries in court. She has a fastest serve this fortnight of just 106mph, compared to 122mph from Williams, and needs to hit the target consistently and on key points with the first ball because her second will inevitably get punished. If Kerber finds her range with upwards of 70 per cent of first serves, and takes nothing off the ball to reach those numbers, then Williams might find cheap points are in short supply.
Kerber said after the 2016 final that she had struggled with nerves in the early stages of that match, but with that experience tucked away in the memory bank she at least knows exactly what to expect, how to handle the formalities and the occasion. Perhaps this time Williams will be feeling it, after her year away from tennis and everything that is riding on this match. Perhaps the 36-year-old will find it particularly emotional, given all that has happened to her since she last walked out for a Wimbledon final. Perhaps, though, the new mother will get down to business as usual, just as she has in her six matches so far.
With a little help from my friends
Williams has been backed by A-list supporters Drake, Jessica Biel and Justin Timberlake this week, and two years ago had Beyonce and Jay-Z cheering her on in the final. This year the Duchess of Sussex is heading to Wimbledon to watch her friend go for glory. And doubtless a large cast of stars will be inside Centre Court for the occasion, as Williams searches for a record-equalling victory.
