Lewis Hamilton has had more success in Shanghai than any other Formula One driver, which makes Sunday's Chinese Grand Prix the ideal location for the triple world champion to end Mercedes teammate Nico Rosberg's winning streak. While Rosberg has started the season with a perfect 50 points from two races, and a run of five successive victories dating back to last November, Hamilton is ready to turn the tables. The Briton has won four times in Shanghai and is on for three in a row after last season becoming the only driver to win the race in successive years.

"Now we go to China for the next battle. It's a track that's been good to me over the years... so hopefully this race can be the turning point." Hamilton has not won since he took his third world championship in Austin, Texas, last October but the 31-year-old has started both races this season on pole position.
