Marion Bartoli compared the debate around Serena Williams' comeback to the one that surrounded Roger Federer's return in 2017, displaying confidence in Williams' ability to challenge for the big titles right away. The former Wimbledon champion dismissed all talk of the American potentially failing to find form upon returning.Back in 2017, 35-year-old Federer returned after a six-month layoff after surgery to win the Australian Open. He went on to win Wimbledon that year as well. Speaking on the Les Grandes Gueules du Sport podcast, Bartoli said that she sees no reason why Serena Williams cannot repeat the same."I don't believe it, the debates remind me of those when Federer returned in 2017. No one thought he was going to win Grand Slam tournaments again, yet he won 3," Bartoli said.Wimbledon@WimbledonIt's on, @serenawilliams 🤝#Wimbledon4627391It's on, @serenawilliams 🤝#Wimbledon https://t.co/f0pGoYE0TFBartoli opined that Williams always holds an advantage against the other players, provided she is fit and in good shape on the court."If she is in good physical shape, she can absolutely go for a result.

It's been 12 months since she played at Wimbledon and got hurt. Now, 127 other women are going to be extremely worried about the draw when it comes out next Thursday, potentially seeing her unseeded," Gilbert said of the 23-time Grand Slam champ's return.The American superstar's world ranking has dropped to No. 1,208.
