Rising star Kei Nishikori said Thursday he needed to emulate US Open champion Andy Murray's new aggressive style of play if he is to challenge the top players in the men's game.
The Japanese player was hailed as a future promise after he won an ATP Tour title in 2008, aged 18, in only his sixth start on the tour and just a year after turning professional.
However Nishikori's win in Delray Beach, Florida, remains his only ATP title to date and he currently ranks 17 in the world, well below Murray whose switch to a more attacking-minded game saw the Scot make his Grand Slam breakthrough earlier this month.
