The match was scheduled for Sunday afternoon, but will now take place on Monday at midday local time.

Heavy rain has been falling for most of the afternoon in Rome and the women's final between Maria Sharapova and Li Na was suspended for two hours earlier in the day. Sharapova went on to win the match 4-6, 6-4, 7-6 (5) as the rain continued to fall.

The crowd jeered the decision to postpone the match as they had sat in the stands waiting for several hours under umbrellas.

"I've been living and breathing tennis every day. I'm looking forward to some days off and getting ready for Paris," said Federer, who is the father of two twin girls. "I'm happy in some ways that the event is over for me. We've got two kids running, they're growing up. We have a lot on our plate. This is the best time of my life and I wouldn't change it for anything. But I like to put the kids to bed and that's impossible with the schedule I've had over the last two weeks. Don't feel bad for me, I'm okay with it all. I've probably had night sessions for the last 10-11 nights, it catches up with you, but at least you can sleep in. I'm not complaining but you need that dinner and time to relax and not have to go to bed right away. It's tough and it's always been that way but I love it."

Federer added that he has had a great clay court season but did not expect to go undefeated in Spain and Italy.

"I knew I wouldn't win both (Madrid and Rome), I actually expected this final (Novak Djokovic vs Rafael Nadal)," he said. I'm just happy the tournament is over for the moment."
