The Kerber fan saying she's injured so she's playing bad, but disregard Serena's injuries throughout the year. So what is it ? Do you accept injury as an excuse for a bad performance now ?
So wether you don't, and you accept the fact that Cibulkova completely exposed her ass today
Or you do, and you accept that Kerber won slams because she benefitted from Serena's injuries
You lose either way.
