Team GB's Andy Murray has stressed his determination to succeed after he defeated Switzerland's Stanislas Wawrinka in the opening round this afternoon.
Murray won the match 6-3 6-3 and afterwards, he reaffirmed his commitment to succeed after he lost in the first round in Beijing four years ago.
Murray told BBC Sport: "In Beijing, I didn't understand what the Olympics meant to me. It was my first time there and I was so excited to be there.
"I went to the opening ceremony and I was trying to watch other sports because I had never experienced it before and maybe didn't focus as hard on myself and my event.
"I know how much that loss hurt me and I wanted to come here best prepared as I could and today was a good start."
Murray will play Finland's Jarkko Nieminen or India's Somdev Devvarman in the second round.
