Winning a Grand Slam is not something I'll think about.
It's always tough when you miss a Grand Slam, especially Wimbledon.
I always said if I had to pick one Grand Slam to win, it would be the U.S. Open.
Hopefully I can just have another terrible year with only the one Grand Slam and that will be just fine.
I am very glad not only to complete the grand slam, but to become Olympic champion alone makes me happy.
I prefer the Grand Slam than the No. 1, but still, to get No. 1, not many players did that, so it's going to be very important for me.
In tennis it's easy to get greedy - and one Grand Slam doesn't feel enough any more.
I think I'm the first 1990-born guy to win a Masters 1000, so it's quite special to be the first one in a very strong group of guys. There are a lot of guys playing great, and hopefully there are going to be a lot more coming.
My victory against Venus was the most special. She's is a multi grand slam champion; her sister is Serena Williams. I was like, 'What is going on?' I broke her five times in a row. She is one of the best servers in the game.
Winning the second grand slam, it was a bit different. I don't have anything to prove anymore. I am at the top: number one.
Winning a Grand Slam was something I was chasing the first day I became a coach.
It's hard to win Grand Slams.
I won my second Grand Slam in one year. That is the best year in my career.
It is never easy for sure against Roger.
