Djokovic: It was no stroll

Novak Djokovic enjoyed a stroll into the second round of the US Open at the expense of Ivan Ljubicic at Arthur Ashe Stadium but insisted it was not as easy as it looked.

The world number four was never in trouble on the way to a 6-3 6-1 6-3 victory over the 30-year-old Croatian in one hour 37 minutes.
