NEW YORK (Reuters) - Top seed Novak Djokovic and number two Roger Federer are favoured to wage another title showdown in the last grand slam of 2014, although some emerging young guns have other ideas for the U.S. Open starting on Monday.

Djokovic and Federer's path to a championship clash could be less troubled than usual with the absence of last year’s winner Rafa Nadal due to a wrist injury, and the sub-par form of 2012 champion Andy Murray since last year’s back surgery.
