So good to see Serena win and return to No 1. The best player in the world is back where she belongs. Didn't see the match, had to head to bed after Murray v Nadal, but it sounds like a cracker.
Here's her reaction from the BBC
"I'm so excited," she said. "This was magical. It was everything coming together like magic. I wasn't even going for number one and it's just like an added bonus. It is that special because I've been working so hard."
Williams has now won one French Open, two Wimbledon, three Australian Open and three US Open titles, adding to her victories of 1999 and 2002 in New York. Asked to compare this US Open to the other two, Williams said they are all special in their own way.
"Each one means a lot," she said. "The 1999 one was special because I knew I was going to win it. I just felt it. I wanted it so bad in 1999. It was my first Grand Slam so no one can take that away. I won doubles that year too."
