French Open: Andy Murray 'surprised' by easy Giraldo win

Andy Murray says he is "surprised" how well he played after beating Santiago Giraldo to reach the last 16 of the French Open - just days after overcoming a significant injury scare.

The fourth seed, who struggled with a back spasm during his third-round win against Jarkko Nieminen, looked in much better physical form as he comfortably won 6-3 6-4 6-4 against the Colombian.

Speaking to BBC Sport's Jonathan Overend, Murray also says he is looking forward to his "tough" fourth round opponent Richard Gasquet.
