Roger Federer believes Novak Djokovic could feel the pressure at the US Open and is predicting an epic tournament at Flushing Meadows.

Djokovic ended a two-year grand-slam drought at Wimbledon last month to win one of tennis’ big-four tournaments for the 13th time.

The 31-year-old has been installed as favourite in New York by some bookmakers, with Rafael Nadal and Federer not far behind.

Federer is excited to see Djokovic return to form but does not know how the added pressure from his Wimbledon win will affect his rival.

Addressing the media before his Cincinnati Masters campaign, he said: “Novak can play with less pressure again I guess, to some extent, but you can always get caught up in the pressure, the media saying ‘well clearly now you’re going to win the US Open’, and you’re like ‘well, I guess so, yes’.
