PARIS (Reuters) - Roger Federer tops the bill at the French Open on opening Sunday when he makes his long-awaited return to the Parisian clay with a first-round match against Italian Lorenzo Sonego.

The 37-year-old Swiss, whose one Roland Garros title came 10 years ago, has been absent from the claycourt Grand Slam since 2015 and says he has missed it.
