The French Open is only one week away, the second Grand Slam of 2014 is set to be a cracker as well.
In normal circumstances, Rafael Nadal would be the only man in contention - he has only ever lost once in nine years after all - but the world no.1 has struggled this year.
Novak Djokovic beat him in Sunday's Rome Masters final, Kei Nishikori was a set up before retiring through injury in Madrid's climax, and the supposed 'King of Clay' was subjected to unexpected quarter-final defeats in Monte Carlo and Barcelona.
Obviously the likes of Djokovic, tennis' most successful patron Roger Federer and even Australian Open champion Stanislas Wawrinka will be among the main challengers.
However, some of the less successful stars on the circuit will sense their chance at glory with some of the big names faltering.
Here we have compiled a list of the top five darkhorses that will look to spring a shock and dethrone King Nadal.
