Monte Carlo is known as a place for the glamorous celebrities who parade their designer threads, however Rafael Nadal is facing some unwanted issues of his own at the Masters.

A wardrobe malfunction with the Spaniard's shorts are causing him to alter his serve routine as he looks to win a ninth title in the principality. and there is nothing he can do to solve the problem just now. The world no.1 is currently unable to retain any balls in his shorts, meaning they simply fall-out the bottom and get in the way.

Nadal is therefore having to request a fresh set from ball-boys everytime he faults a first serve.

"The ball comes out of the bottom of them and gets in the way," he told a Reuters source.

"We'll try to sort it out for the next tournaments but here it won't be possible.

"When you have been doing something the same way for so many years, when there is a change you have to think about it and it makes things a bit more difficult.

"But it's better to do it that way than have the ball popping out of the bottom of your shorts which is quite uncomfortable."

Nadal is wearing kit by American giants Nike, who sponsor the athlete. They will need to make improvements before more Masters events in Madrid and Rome before the French Open kicks-off at the end of May. Fortunately for the 27-year-old, though, the pocket problem isn't proving to disrupt his overall game as he cruised into the quarter-finals without losing a set.

A tussle with fellow countryman and clay-court specialist David Ferrer takes place today on Court Central.

He brushed past Russian minnow Teymuraz Gabashvili in round two with a 6-4 6-1 win, after receiving a bye, along with the other top seeds, through the first stage. Italian clay specialist Andreas Seppi was then demolished 6-1 6-3.

Victory over Seppi made sure he passed another milestone in a hugely successful career to date. The 13-time Grand Slam champion recorded his 300th win on clay and he is only the 11th man to complete the feat.

Nadal is currently searching for a ninth title in Monte Carlo. World no.2 Novak Djokovic ended his eight-year winning streak last year with a straight sets win.

A ninth title will also be on his agenda at Roland Garros. No man has ever won in Paris more than eight times but Nadal is one of the greatest clay court specialists to ever grace the sport and as such; he has become known as the 'King of Clay'.

The Manacor-born star is facing one of his toughest seasons on the clay as Djokovic looks to gain the upper hand the duos' rivalry and leapfrog him into the world no.1 spot.

Monte Carlo's reigning champion has won the last three meetings between the pair, including a final win a few weeks ago at Miami's Sony Open.
