Scot prepared for test
Andy Murray insists that his match with Gilles Simon will be a tough test as he looks to progress to the quarter finals.
The world number 16 was made to work by Gael Monfils, winning 6-4 6-4 4-6 1-6 8-6 in a match that ran for almost five hours.
Murray has continued his fine form that saw him end 2012 with a gold Olympic medal and a first Grand Slam by breezing through the opening four rounds without dropping a set.
The head-to-head between the two opponents will make easy reading for the world number three, who has won nine times since their first meeting in 2007, dropping only one set during that time.
The Scot knows that it may not be a walk in the park, pointing to the fact that Roger Federer was taken to five sets by the Frenchman at this tournament in 2011.
"He's caused guys lots of problems before," said Murray.
"He pushed Roger to a very tough five set match here [in 2011]. He's getting closer to the top 10 in the world. He had his own injury problems as well."
