ANDY MURRAY will draw on the memories of the two biggest days of his career when he takes on Novak Djokovic for a place in the semi-finals of the US Open.

Today’s match will be the earliest ever meeting at a grand slam for the two former junior rivals, who were born just a week apart and rose through the ranks together.

With Murray only seeded eighth following his drop down the rankings, the danger was that he would come up against Djokovic or Roger Federer in the quarter-finals, and so it has proved.

Djokovic leads the overall head-to-head 12-8 and won their only previous match this season in Miami in straight sets.
