Sky Sports' Annabel Croft will be analysing the matches at the US Open from next week - but she has already sunk her teeth into answering YOUR questions.
FALTERING FED
What do you think of Roger Federer's form going into the US Open and what are his chances of winning? @olumcjobson
ANNABEL REPLIES: You can never underestimate a great champion as they can find another gear when it really matters, but he is coming in with the least amount of form he has had for a number of years and the least amount of confidence. He did resurrect some form and confidence, though, in his quarter-final with Rafael Nadal in Cincinnati but I think we could be in for a bit of an upset in New York.
SLOANE FLAIR
Do you think Sloane Stephens is ready to take over from Serena Williams as American number one? Melanie
ANNABEL REPLIES: Sloane is not going to overtake Serena yet but she is definitely a massive star of the future and has more than proved herself on the big stage. She has made enormous progress since she beat Serena in the Australian Open earlier this year and made the quarter-finals, and I have only been impressed by the way she has developed. I really like her game, I think she is a great athlete and she brings a lot of character and personality to the court.
BEST OF ALL TIME
Who do you think are the greatest male and female players of all time? Ricky
ANNABEL REPLIES: I would have to say Federer for what he has achieved in the game but my favourite tennis player in the men's game and the guy who inspired me to take up the sport was Bjorn Borg; he took tennis to superstar status and brought in teeny-bopper fans for the first time. In the women's game, Margaret Court has the record of 24 Grand Slam singles titles, and Martina Navratilova has won lots, too, but it is hard to look past Steffi Graf for her athleticism, the way she played the game, all she brought to a tennis court and 22 Grand Slams in the Open era.
